I love going to Spa World -- the communal bath is so relaxing, and the multiple dry saunas are bliss. I like the restaurant as well -- good food well prepared. We stayed for 8 hours.
We had a lovely Japanese head spa treatment at Rosewood Spa! The treatment included aromatherapy, massage, two shampoos, a deep conditioner with steam, then blow dry. The tables are very comfortable and the treatments were relaxing.
