We booked the Thermal Suite pass for our cruise as we had an inside cabin and wanted somewhere we could lounge around and enjoy the views without kids around. We enjoyed using it daily, the staff were friendly and everything seemed to be kept fairly well. Other guests were often inconsiderate in their volume (having shouted conversations rather than a normal indoor volume!) which is annoying when trying to relax. Loved the heated loungers. Would recommend unless you have mobility issues as the pool and hot tub were tricky to enter and exit. Would love to see an encouragement for guests to respect each other with regard to volume and for the suite to be tech free - people watching videos on their devices there was inconsiderate and disturbing to others.
