Has anyone taken the Vision OTS to Alaska? We were on the Vision last year in Mexico, and will be taking her again this Sept. to Alaska. I know that the solarium on the Vision has a closable roof, do they close it during the Alaska voyages and allow swimming? What do they do with the main pool area? I know it is much too cold to swim outside, so do they just cover up the outside pool area but keep the solarium open and heated?
