Westin Kierland Day Pass: Adults Can Still Book the Spa. Families Have to Wait.
The Westin Kierland day pass earns a depends verdict, and families should wait. As of September 25, 2026, pool day passes were bookable only through September 27, 2026. No pool inventory was loaded on ResortPass through March 13, 2027, or on Marriott’s iDayPass through March 31, 2027. For adults, the 18+ Spa Pass at Agave, The Arizona Spa, is the only way in. It includes the adults-only Aguamiel Pool on both channels but not the main pool complex. It ran $95 to $115 before fees on dates we checked from September 27 to October 23, 2026.
Can you still buy a Westin Kierland pool day pass?
As of September 25, 2026, Kierland pool day passes were bookable only through September 27, 2026. We checked both official sales channels. On ResortPass, the pool Day Pass showed zero inventory on every date we sampled from September 28, 2026, to March 13, 2027 (ResortPass booking backend, checked September 25, 2026). On Marriott’s iDayPass portal, the General Pool Entry pass had no inventory loaded from September 28, 2026, through March 31, 2027 (iDayPass, checked September 25, 2026).
Neither channel says the pass is paused, and neither gives a return date. The timing lines up with the resort’s renovation. Marriott says the lobby is temporarily closed and the Adventure Pool and lazy river are being renovated from September 8, 2026 (marriott.com, checked September 25, 2026). Marriott Vacation Club’s page for the neighboring Westin Kierland Villas says the Adventure Pool is expected to reopen on October 17, 2026. The same notice says the lazy river and waterslide stay unavailable through January 2027 and that reopening dates are subject to change (marriottvacationclubs.com, checked September 25, 2026).
A reopened Adventure Pool does not mean pool passes are back on sale. Check both channels again after October 17 before you plan around it.
What does the Westin Kierland Spa Pass cost?
The Spa Pass is the one day-use product still selling on every date we checked. It ran $95 to $115 per adult before fees on dates we checked from September 27 to October 23, 2026. The two channels price the days differently, so the cheaper channel depends on your day.
On ResortPass, the Spa Pass was $95 on every Monday through Friday we sampled and $115 on every Saturday and Sunday (ResortPass booking backend, checked September 25, 2026). ResortPass then adds its service fee. It was exactly 12% on every Kierland Spa Pass booking we checked, across four carts built September 25, 2026. Arizona sales tax of 8.05% applied to the pass price only, not to the fee.
On Marriott’s iDayPass, the Spa Day Pass was $95 Sunday through Thursday and $115 on Friday and Saturday, on every date from September 25 to October 24, 2026. The portal quoted $108.40 with taxes for a $95 date (iDayPass, checked September 25, 2026). We did not complete an iDayPass checkout, so we cannot confirm whether other charges apply at payment.
Westin Kierland Spa Pass: True Cost for Adults
What does the Spa Pass include, and what does it leave out?
The Spa Pass covers Agave, The Arizona Spa, and the adults-only Aguamiel Pool. Both channels list the same core items and the same two limits (ResortPass and iDayPass listings, checked September 25, 2026). Guests must be 18 or older, and the main pool complex is not included.
| Amenity | Status | Notes |
|---|---|---|
| Aguamiel adults-only pool | Listed on both the ResortPass Spa Pass and the iDayPass Spa Day Pass. Open 6 a.m. to 10 p.m. daily for guests 18 and older (iPoolside, checked September 25, 2026). | |
| Whirlpool hot tub | Listed on both channels. | |
| Eucalyptus steam room and dry sauna | Listed on both channels. | |
| Locker room with showers | Listed on both channels. | |
| Fitness classes | Listed on both channels. iDayPass describes them as select modalities. | |
| Relaxation and tranquility rooms | Listed on both channels. | |
| Spa treatments | Menu pricing | Available for purchase. Agave takes treatment bookings at 480-624-1525 (marriott.com). |
| Adventure Pool Complex | Excluded from the Spa Pass on both channels. Expected to reopen October 17, 2026, subject to change. | |
| Lazy river and 110-foot waterslide | Unavailable through January 2027, subject to change (marriottvacationclubs.com, checked September 25, 2026). | |
| Parking | Hourly self-parking from $10 to $30, valet $45 daily (marriott.com, checked September 25, 2026). Free parking with a food purchase appears only on the pool Day Pass listing. | |
| Outside food and coolers | No policy is published on ResortPass, iDayPass, or iPoolside. Confirm with the resort before arriving. |
Check-in reality: what happens when you arrive
Do not head to the lobby. Marriott says it is temporarily closed during the renovation (marriott.com, checked September 25, 2026). The ResortPass Spa Pass listing sends you to the Adventure Pool Front Gate on Saturday and Sunday. On Monday to Friday, you check in at J. Swilling’s Pool Bar & Grill. Bring a photo ID or your booking ID (ResortPass listing, checked September 25, 2026).
Pool hours depend on which official page you read. Marriott’s iDayPass pool listing gives pool entry hours of 10 a.m. to 5 p.m. The resort’s iPoolside page lists Adventure Water Park hours of 9 a.m. to 7 p.m. daily, and ResortPass shows the same 9 a.m. to 7 p.m. (all checked September 25, 2026). For a spa visit, the hours that matter are the spa’s own. ResortPass lists Agave at 8:30 a.m. to 4 p.m. daily.
The FlowRider surf simulator is a question mark. The iDayPass portal’s renovation notice says FlowRider access comes with the day pass, but the same portal’s product text still lists it as an extra fee. With no pool pass on sale, it does not affect a Spa Pass visit.
Best for and skip if
- Adults who want a quiet pool day · The Spa Pass includes the heated, adults-only Aguamiel Pool on both booking channels, away from the renovation work at the Adventure Pool.
- Spa seekers · Steam room, dry sauna, whirlpool, locker room, and fitness classes are all included. Treatments are extra.
- Scottsdale locals on a weekday · A weekday ResortPass Spa Pass came to $114.05 at checkout in our September 25, 2026 cart, before parking.
- Families with kids · The Spa Pass is 18+ only, and no pool day pass was on sale after September 27, 2026. Look at a Scottsdale-area resort that is selling family pool passes instead.
- Anyone who wants the main pool · The Adventure Pool Complex is excluded from the Spa Pass on both channels, even after it reopens.
- Lazy river and waterslide fans · Both stay closed through January 2027, and Marriott says reopening dates are subject to change.
What to bring and pro tips
Book the Spa Pass on the channel that is cheaper for your day. ResortPass charged $95 on Fridays and $115 on Sundays in our samples, while iDayPass did the reverse (both checked September 25, 2026). Weekday visits are the cheapest on both.
Plan your parking. Only the pool Day Pass listing offers free parking with a food purchase, and that pass is not selling. Marriott.com lists hourly self-parking from $10 for up to 3 hours to $20 for 6 to 10 hours (checked September 25, 2026).
Call ahead about food. The resort does not publish an outside food or cooler rule on any booking page we checked, so confirm it at 480-624-1000 before you pack anything. J. Swilling’s serves food from 11 a.m. to 5 p.m. daily.
Bring sun protection and a water bottle. The Aguamiel Pool is outdoors.
The better alternative for families
Families who want a Scottsdale-area water park day have better options while Kierland’s pool passes are off sale. Our Phoenix and Scottsdale resort day pass comparison prices five resorts side by side. For how Marriott sells day access across its brands, see the Marriott day pass guide. Before booking on ResortPass, read how ResortPass works for the checkout fee.
Arizona Grand Resort & Spa in Phoenix sells a Day Pass for its Oasis Water Park, with a 950-foot lazy river, wave pool, and 8-story slide tower. It was $55 per adult on September 28 and October 3, 2026, and $65 on October 10 (ResortPass, checked September 25, 2026). Grand Hyatt Scottsdale Resort sells a Day Pass with 10 pools and a 3-story waterslide. It was $50 per adult on September 28 and $70 on October 3, 2026 (ResortPass, checked September 25, 2026). Both add ResortPass’s service fee at checkout.

If you want the Adventure Pool once it reopens, an overnight stay includes pool access that a Spa Pass does not.
