My situation is just the reverse of yours; I've finally talked my husband into going on an Alaskan cruise next summer (after 30 cruises) and I'm very excited. He always said he didn't want to go any place where it was cold or it rained a lot on vacation, but I've finally talked him into Alaska. I always plan the cruises and then he usually just says, where are we going this time? I've been on Carnival, Princess, RCCL, NCL, Disney and the old Constitution that went to Hawaii. In my opinion, you really can't go wrong with the first three cruise lines I mentioned. NCL, I've had some problems with, so I really don't recommend them; although I've been on 5 or 6 cruises with them. We're booked on the new Island Princess for next summer and all of the Princess ships I've been on have been great; as well as all the RCCL ships I've been on. We took Carnival to Bermuda this summer and it was a new ship (Pride) and just loved it. The only times I've not had a good time on Carnival, was the two or three times we were on a older ship, and it was not a good cruise. Now, I just book the new ships. I know some people say the older ships have charm, etc.; but from my experience, the problems associated with cruising on an older ship just doesn't justify going on one. That's just my opinion. Do some research on the boards, like everyone does, and I'm sure you'll make a good decision.
Happy Cruising.....Anita
