RCL's Serenade in Alaska this month

[tee-three]

We are going on the Serenade in Alaska this weekend, and all of a sudden, thanks to some posts here, I am concerned about the crib-availability. Our youngest is 15 months - is it a pack & play? Do I need to bring our own sheets? Should I go and get a pack & play to bring, rather than trust the ship to have a reasonable one available?

 

We're traveling with our three year old, our almost-seven year old, and Princess Baby (she's the 15 month old), and we're in a family suite. We're doing the rainforrest sanctuaty in Ketchican and the whale cruise in Juneau, and a dogsled adventure in Skagway - any thoughts on those excursions, or about the Serenade itself? And has anyone had any time to visit the spa? I supposedly will get a 2 hour break if the camp is good for our 3 year old, and wanted to try something interesting.
