Key West Resort Day Passes: $20 Budget Pool to $80 Private Beach

Key West sells a resort day pass at five clearly different price points. The gap between the cheapest and most expensive is not driven by pool size alone. It comes from location, beach type, and which extras each property bundles into the base price. This guide breaks each one down so you can match the pass to your actual day, whether that is a cruise port stop, a post-checkout afternoon, or a full daycation.

Quick match: which pass fits your day?

• Budget pool day with extras: Havana Cabana at $20 adult, hot tub included
• Two pools plus a parking solution: Blue Flamingo at $25 adult, Park and Ride available
• Only natural private sand beach on the island: The Reach at $40 adult
• Largest private beach plus dual pools: Casa Marina at $50 adult
• Three heated pools and South Beach: Southernmost Beach Resort at $50 adult
• Spa access near Mallory Square: Pier House at $75 to $80 adult

All prices are pre-fee base prices from the ResortPass booking backend (verified August 2026). ResortPass adds a service fee at checkout that is not reflected in those figures.

Havana Cabana Key West: $20 for Key West’s largest pool

Havana Cabana sells the cheapest day pass on ResortPass in Key West. Adults pay $20 and children pay $15 on weekdays, rising to $25 for children on weekends (ResortPass, verified August 2026). The pass covers access to what the property markets as Key West’s largest pool, plus the hot tub, the Mojitos Pool Bar, and Cuban food from the Floridita Food Truck. Bicycles and vintage Vespas are available on site (ResortPass listing, verified August 2026).

The pool setup is the draw here, not a beach. There is no beach access included. If you want sand and surf, this is not your property. For a couple wanting a full afternoon poolside with handcrafted mojitos and a hot tub, Havana Cabana is hard to beat. Two adult passes cost under $50 combined before the service fee.

The Family Pass bundles four people for $65 on weekdays and $95 on weekends (ResortPass, verified August 2026). That makes it one of the stronger family value propositions in the city when a waterpark is not a requirement.

Blue Flamingo Resort: $25 two pools and a parking hack

Blue Flamingo, the recently renovated former Gates Hotel, offers Key West’s most distinctive day pass add-on: a Park and Ride Pass at $15 per day (ResortPass, verified August 2026). That is significant. Downtown Key West parking runs around $6 per hour on Duval Street as of January 2026. Parking for four hours already exceeds the cost of the Park and Ride pass.

The day pass itself costs $25 per adult and $10 per child on weekdays (ResortPass, verified August 2026). It covers two pools and access to the resort’s two tiki bars, Rum Row and Toasted Coconut, which serve handcrafted cocktails and tapas (TripAdvisor reviews, verified August 2026). There is no beach. The two-pool setup and lively tiki-bar energy make it a strong choice for a social group day rather than a quiet beach retreat.

Monroe County locals get a discounted pass at $20 per adult. Active military pay $15 (ResortPass, verified August 2026).

The Reach Key West: $40 for the island’s only natural sand beach

The Reach holds a single geographic distinction in Key West: it sits on the only private natural sand beach on the island (ResortPass listing, verified August 2026). Every other resort in this comparison either has a constructed beach or no beach at all. That distinction is worth money to the right buyer.

The day pass costs $40 per adult and $30 per child. That price was consistent across every weekday, weekend, and Friday date sampled (ResortPass, verified August 2026). The pass covers pool access, the natural sand beach, and the Four Marlins restaurant for food and drinks on a pay-as-you-go basis. The resort is one block from Duval Street and steps from the Southernmost Point. That location makes it a practical base for beach time combined with a walk into town.

The Reach also sells a “Day at Port Pass” at $65 per adult, which appears to bundle additional access for cruise visitors (ResortPass, verified August 2026). If you arrive by ship, that product is worth checking against the standard pass to see whether the extra inclusions justify the premium.

Casa Marina Key West: $50 largest private beach plus two pools

Casa Marina is the more expansive Hilton Curio sister property to The Reach. It holds the island’s largest private beach plus two separate oceanfront pools: one designated for family use and one adult-only (resort website, verified August 2026). The day pass at $50 per adult and $25 per child was consistent across every sampled date, weekday and weekend (ResortPass, verified August 2026).

The inclusions are the most clearly documented of any property in this comparison. The resort’s own day-pass page confirms private beach and two pools, poolside lounge chairs and towels, and full fitness center access (resort website casamarinaresort.com/recreation/resortpass/, verified August 2026). It also includes access to three dining venues: Dorada, The Canary Room, and Morrison’s Market. Complimentary poolside refreshers such as ice pops and sunglass cleaning are listed as well. Spa Al Mare is on site, though spa treatments are pay-as-you-go and not included in the base day pass.

For a family that needs a fitness center and wants confirmed towel service without having to ask, Casa Marina is the most straightforward pick at this price point. At an average overnight rate of around $429 per night (HotelsCombined, August 2026), the day pass at $100 for two adults represents a fraction of the overnight cost.

Southernmost Beach Resort: $50 three pools and South Beach

Southernmost Beach Resort matches Casa Marina’s $50 adult price but with a different asset mix. It offers three heated pools instead of two, beach access at South Beach rather than a dedicated private beach. And the Southernmost Beach Cafe for poolside food and drinks (ResortPass and resort website, verified August 2026). The $25 child price also matches.

Three pools is a meaningful advantage for families or groups that want options. The resort is tucked in historic Old Town on Key West’s Atlantic Coast. South Beach access gives day-pass holders sand and water. The listing also confirms a spa and fitness center on site, though those are not enumerated as included in the day pass itself. Confirm inclusions directly with the property before booking.

The Day Room product is available on weekdays at $250. That is useful for travelers who checked out of a different hotel and need a private space to shower and rest before a late flight. Not available on most sampled weekend dates.

Pier House Resort and Spa: $75-$80 pool, beach, and spa near Mallory Square

Pier House is the highest-priced standard day pass in this comparison at $75 per adult on most dates and $80 on at least one Saturday (ResortPass, verified August 2026). Children pay $35. The location is what drives the premium: the resort sits steps from Mallory Square, putting it directly at the center of Key West’s most visited area.

The pass covers pool access, the private white sand beach, beach umbrellas, beachside drinks access, and sun loungers. The Spa at Pier House offers deep-tissue massage, thalassotherapy, and body wraps (Hotels.com and Expedia, verified August 2026). Spa treatments are not included in the day pass price; they are pay-as-you-go. The resort’s Chart Room Bar operates on site. The Chart Room is one of Key West’s historically notable bars, which adds a genuine local-culture dimension to the day.

At $150 base for two adults before the service fee, Pier House is harder to justify purely as a pool day. It makes the most sense for a visitor who wants the Mallory Square location. It also suits anyone who plans to use the spa as a paid upgrade, or who wants beach access near the cruise terminal.

The room math

Key West hotel rooms are not cheap. Casa Marina averages around $429 per night (HotelsCombined, August 2026). The broader Key West market starts around $141 at entry-level properties and reaches well above $400 at resort-class hotels (Tripadvisor, verified August 2026).

Two adult day passes at Casa Marina cost $100 before the service fee. That is under a quarter of the typical overnight room rate at the same property. Even after adding the ResortPass fee, a modest food spend, and whatever parking costs, you are unlikely to exceed $200 for a couple at this property. That math holds at every property in this comparison.

One scenario where booking the room beats the day pass: families of four or more visiting for multiple days. The cumulative pass cost across several adults and children compresses the overnight rate gap. At Pier House, two adults and one child cost $185 base on a weekday before the service fee. That is approaching one third of a room rate before the second child is added.

For cruise port stops and single-day visits, the day pass wins on math at every property in this comparison. The break-even question is simpler in Key West than in most cities. Even the most expensive pass here at $80 per adult is a small fraction of the typical room rate. The calculation changes only for groups where the headcount is high and the visit is multi-day.

Check-in reality

ResortPass functions as the booking layer for all five properties. You book online, receive a confirmation, and check in at the hotel’s front desk. The check-in experience varies by how well each property integrates day-pass guests into its daily operations. Properties that run high day-pass volume tend to have a smoother system. Reading recent property-specific reviews on ResortPass before booking gives you the clearest read on current check-in conditions at each hotel.

One practical note: Key West parking is expensive. Street parking on Duval Street runs around $6 per hour as of January 2026 (visitor reports, verified August 2026). If you are driving to any of these properties, factor in parking before calculating your true daily cost. Blue Flamingo’s $15 Park and Ride Pass is the only day-pass product in this comparison that explicitly addresses parking. It undercuts hourly street pricing for any visit longer than two and a half hours.

Cancellation policies and check-in window hours vary by property and are set by the individual hotel, not by ResortPass. Confirm check-in and checkout times in your booking confirmation. Most Key West day passes run until late afternoon or sunset, but exact hours change by season and property.
