I have a dummy booking that I am going to switch to the 2014 Alaskan cruise. I had planned to do July 7th based on what I've read regarding weather, wildlife, etc. I am very tempted by the 9 night offering though. That is for a May 24th sailing. Can anyone with experience in May and/or July give me guidance. Will getting the extra 2 days and the Sitka stop be worth it for a May trip vs. July? If it isn't obvious I've never cruised Alaska before! TIA!
