Thanks all. That helps. For our 8 day cruise, they looked like they were offering multi-day passes. I was looking at the 3 day pass for $29.99. So less than if I took 3 classes at $20/each. But when I clicked, it says it is not available after all. I may keep checking.
As for RWDW1204, I realize not everyone goes on a cruise looking forward to fitness classes. See you by the pool. ?
