Oh my goodness, my husband and I book the balcony Spa and that price is for the thermal spa...so enjoyable and relaxing and adults ONLY !! There is no judgement on body types, just pure relaxation. The pool is small, but with many jets that are pressured to target your neck, back and lower legs...it's awesome. There are 3 or 4 different sauna's....my favorite is the salt sauna, but I do into the dry heat one first then the salt cool down one, but there is a steam one too that makes you all sweaty, but it is suppose to open up all your pores.
There are locker rooms for men and women and you can keep your belongings under lock and key...very safe. You walk into the spa and there is complimentary herbal tea and water with oranges floating...very soothing. Then you lay down on the heated tile loungers....very relaxing.
My husband and I actually pack our suits in our walk on bags, so we can head right there when we board (after lunch of course), because your luggage may take several hours to get to your cabin. And plus it will be quiet at that time....
You will totally enjoy this luxury....worth the price and actually that is really cheap, because I have seen it be $399 for the trip per person....so grab that price !! Have a blast !!
