Alaskan Cruise

When my friend and I had lunch today we were talking about going on an Alaskan Cruise. She was wondering if it would be cheaper to cruise if we had a group of about 8 couples so we went and saw a travel agent and she gave us an idea on the prices. Wow, we would have to save up alot of money between now and a year from now. It's not cheap but I hear it's worth it.
