I did the complete spa day package last time I was there. It was heavenly! I thought it was worth every penny! It is such an upscale, relaxing atmosphere. I enjoyed it as much as Elizabeth Arden in NYC. Have a great time!
Oh - I have also had the aromatherapy massage and wrap and the aromatherapy facial - the best spa treatments I have ever had. I don't think there are included in the full spa day package, but they might be good alternatives (and I don't think quite as expensive).
