They left out Oceania cruises. These are two of the Renaissance ships that went out of business less than 2 years ago. They hold about 670 passengers, so they're not real small, but certainly a lot smaller than the biggies that easily carry over 2000 of you nearest and dearest friends!

I'll be on their inaugural cruise this July, from Barcelona to London.

Thanks for the post. Personally, I think small ships are the only way to go! :-) http://www.oceaniacruises.com
