Check with them and pls share yr experience.

I wish I could try the new one at GH, but when I was there last week, they said the new spa won't be ready until late July/early August. The temporary ones are guestrooms converted into massage rooms. Not pretty.
I tried 3 spas in Bangkok and one in Hua Hin. They are CHI in Shangrila, Sheraton Grande and VAREENA in Westin and ANANTARA in Hua Hin.
The best one - in terms of treatment and facility, is by far, CHI at Shangrila. The treatment room is bigger than the size of most guestrooms. The tub filled with petals of flowers is wonderful - the private steam room with colored-light therapy is interesting. I had a 3 hr treatment and absolutely loved it. Each treatment room has a dressing room, a glass covered garden, a giant "over-flowing" tub, double sinks, a toilet, and a steam room. It's HUGE!
VAREENA spa is brand-new. It's not bad. They have a ridiculously large treatment suite, which is in the corner of the building. INMO total waste of space. Sheraton's spa looks very dated and old. It needs a face lift.
The ANANTARA spa in Hua-Hin is quite lovely. The single treatment room has an outdoor rain-shower - but the many windowed-room could be a little too bright for a massage, even with the drapes drawn. But then again, they do cover your eyes with a mask...
In terms of therapists, I found them all to be very good. Both VAREENA and Sheraton's spa have no male therapists, but CHI and ANANTARA do.
I am in Bali now and have so far tried 4 spas. I should post them under separate threads, I would imagine...
