I am not counting on getting much time on the climbing wall, because there will be thousands of folks on the ship and only a few can climb at one time. Same with their Flow-Surfing-Thingamajig. You can burn a lot of calories ice skating, though. (The rink won’t have much room for jumps but you might be able to get a spin in.) And as founder of the Elevator Temperance Brigade, I absolutely do want to continue it this year.
