Interested in doing this ourselves. Does this get you unlimited access to the spa for the entire cruise? How does this work exactly? We went for an hour slot on our last cruise and it was nice but I actually enjoy the Carnival and MSC thermal areas much better mostly because of the extremely small 1 person hot tub and cold tubs that VV has in the area. And the "hot tile area" is just a flat piece of marble that was luke warm at best and very uncomfortable on VV compared to the nice tile lounger on the other lines. Wish they would correct this space.
