The Dream thalassotherapy pool after dry dock?

[Ocean Spirit]

I've heard both pro's and con's about the thalassotherapy pool on the Dream. I was wondering if anyone has used it since the dry dock. I've been wanting to try it for a long time but they want $50 for a day pass. I don't want to spend that much money if the jets are working right or the water is yucky. We won't be getting off the ship at one of the ports and thought it might be relaxing to spend the day in the spa.
