Might be too late for your cruise to Alaska, but I'll give it a try! I've been on 2 Carnival Cruises and 20 Holland America cruises. Three HAL cruises to Alaska. Just came back from an Alaska Land Tour I put together myself.
If still interested contact me ASAP, and we can discuss crusing to Alaska on HAL?
PS: Alaska is awesome! Can't get enough of it! Cruises are a Teaser for you to come back and your own Land Tour!
