Alaska Cruise Questions

[tjsmama]

We are going on an Alaska cruise next June and I am curious as to how different the activities on board an Alaska cruise vs a Caribbean cruise (which is what we normally sail) will be. Has anyone cruised to Alaska (recently) and can tell me if they still offer the same activities...ie trivia, karaoke, themed events, etc? I am assuming the menu will still be the American Table menu, but do they add more seafood options on an Alaska cruise? How many shows do they do during a 7 day cruise? Are the shops on board the standard Carnival shops or are they different? Since we do not leave the US (until the last stop in Victoria, BC) are the shops still considered duty free? Has anyone been on the Spirit? I know it has been in Sydney, and not Alaska but curious about the ship since it will be switching to Alaska for the next summer season.

Any information/tips/helpful hints will be greatly appreciated.

As this is specific to Carnival operations and procedure, I would be asking on the Carnival board.
