I'm trying to select an Alaskan cruise for August 2009 and I'm a little overwhelmed! There will be six of us - myself and my husband, my parents, and my brother and his wife. We won't have any kids with us. I think my parents would prefer a larger line. I've been leaning toward Celebrity based on some of the comments I've seen online. Specifically, I've been focusing on either the Celebrity Infinity 7-day out of Seattle or the Celebrity Mercury 7-day out of Vancouver. The Infinity looks nicer/newer, but I've seen a few comments about problems with the ship, causing cancellations. Is this still an issue? This would be a MAJOR bummer for us (as I'm sure it would to anyone - but I REALLY want to try to avoid having this happen, as it is a minor miracle that all six of us will be able to get away simultaneously). Any preference between these two cruises? Or suggestions as to others that you think would be better? Thanks so much for any insight you might have!!
