Swimming on Cruise ships in Alaska?

[Shmoo here]

Is it warm enough to swim in the cruise ship pools while cruising in Alaska? Do any ships have covered or indoor pools? Thanks for your help!

 

This was on our HAL Alaska cruise last year (early June) in Haines. They had the retractable roof partly open because the weather was so nice.

I just went on an Alaskan cruise and people were always in the pools because they are heated!

A hot tub in cool weather can be very comforting.
