Hours and best times to book
Per the hotel's wellness page, standard posted spa hours are Sunday–Thursday 10:00 AM–6:00 PM and Friday–Saturday 10:00 AM–7:00 PM. The property has also published an alternative spa menu PDF listing 10:00 AM–8:00 PM daily; if exact times matter for your visit, confirm with the spa directly.
Because the spa is adult-only and Mondrian runs wellness programming during the week and weekends, mid-morning weekday slots often have more availability than weekends.

Practical tips for your spa visit
Arrive at least 15 minutes before your appointment to use the relaxation lounge and steam/sauna if included. Bring photo ID to confirm age (spa is 18+); the hotel enforces a minimum check-in age of 21 for the reservation holder but that is separate from spa access.
If you plan to visit the pool the same day as a spa treatment and you are not staying at the hotel, check pool availability for Mon–Thu when you confirm your appointment. If you want private time, ask about the couples' suite and whether you can include balcony use in your booking.
- Arrive 15+ minutes early to change and relax
- Bring photo ID to confirm you are 18+
- Confirm whether steam/sauna use is included with your treatment
- If non-hotel guest, verify pool access Monday–Thursday before arrival
| Before you go | Why it matters |
|---|---|
| Confirm spa hours | Hotel pages show two different posted hours in places |
| Check treatment inclusions | Some services include steam/sauna/relaxation time |
| Ask about pool access | Non-guests: pool use Mon–Thu only and availability-based |
