Thanks all, for your input. Because of the cabin size differential vs. Navigator, we opted for Cat. C, and we've got the shower problem covered with a "remodeled" new shower. DH is 6'4" so that's important, even though 1st choice was starboard and only port was available in that category.

A Signatures reservation is definitely a first priority along with bridge, engine room control and galley tour! This cruise promises to be so busy I don't know how much promenade sitting time will be available, but I'll check it out. I have a feeling that I'll be in the Observation Lounge during Hubbard Glacier and he'll be outside with the camera; as much time as he's "played" with it, we'd better have some awesome pix!

Departing 7/19 for Vancouver, 4 night post-ccruise Denali, arriving ATL 8/1 and hope to have a wondrous tale to tell! :D
