Hi Debbie,
Having only been on "Ocean" Princess I thought she was a beautiful ship and I really love doing the southern itinaries. Just look at the different ports and decide by that, unless that is not a factor. From all the reviews I've read all seem to be nice ships. I found the food and service on Ocean to be excellent, would go on here again any time. Enjoy what ever Princess ship you end up cruising on :-)
