Schedule ar least 1 spa treatment, but then you can go early and/or stay and enjoy the amenities at the spa.
The Spa has an amenities pass you can purchase, otherwise you must have a spa service to use the amenities and/or the cafe within the building. As for the rest of the resort, you'll need to be a member, or have an overnight stay to take advantage of the amenities.
No, just have a spa treatment scheduled.
