I went for a tour on Thursday and the place is really really nice. From what I gather because the hotel and spa are operated by different companies you will need to get 2 memberships. One for the pool and beach club (Hotel) and another for the spa (gym). In saying that the spa will be open to anyone on a pay as you go basis. Even if you take the membership the treatments are not included - you will get a discount though.

Tghe membership fee sounds about right 18,000 but there is only a 7,000 registration fee (if I remember correctly)
