It’s a hydro therapy pool and it’s very warm and bubbly. There are metal rollers you can lie on and just relax or there are jets of water you can stand under and they are great for tense shoulders. I have arthritis and I book the thermal suite on every cruise it really is wonderful. When you are done in the pool you can use the heated ceramic loungers in the relaxation room, also very calming. There are showers to use also when you finish. To me it is worth every penny. Linda
