What would you like to know? I have been on dozens of cruises, including 3 on Celebrity. Every cruise line is different and has its pluses and minuses. Celebrity is big on dining and entertainment and in the past has been attractive to a more formal (read older) patron than say Carnival. It is also more expensive. I really liked Celebrity due to its emphasis on food quality and presentation.

Other cruises such as Princess are good because they offer good value as stated above. I like Princess because they have a laundry (self-serve) which allows me and my wife to travel with roll aboards and wash our clothes as needed, saving much distress and time especially on international trips.

Foriegn cruise lines such as Costa are fun because the clientel is so diverse and it makes for a very international flavored trip. The food tends to be pretty good as well. However, be prepared for lots of smokers!

If you want, feel free to PM me and I will try to give you any relevent experience I may have with a particular cruise line.

BTW, if we are talking about any other type of "cruising", then I am not the person to ask. I have been drydocked for decades.
