buzz&woody'smom,
We have been on the Carnival Imagination (4-days), Elation (7-days), and the Triumph (2-days). Also on the Majesty of the Seas (4-day) and the Explorer of the Seas (7-day) and on the Magic twice. Are scheduled to go on the Carnival Legend for 8-days out of New York July 2003.
None of them was a "floating college boat". The food & shows were better on RCCL, but the ships that do the shorter cruises are the Sovereign of the Seas (3 & 4 days from Port Canaveral to Nasasau & CoCo Cay), the Majesty of the Seas (3 & 4 days from Miami to Nassau, CoCo Cay and Key West), the Monarch of the Seas (4 & 5 days from Ft. Lauderdale) and the Enchantment of the Seas (4 & 5 days from Ft. Lauderdale). The major difference we found on the Majesty was that the rooms were very small. Other that that we had a great time, plus there is a casino and other "adult" adventures.
The Carnival Imagaination was our first cruise. We had a very good time there too, and the prices tend to be lower, although you can get some fantastic deals on the shorter RCCL cruises. We just booked some clients on the Sovereign for three days at $165 per person!
The Carnival rooms are much bigger than the RCCL ships mentioned above. The ports are pretty much the same.. Cant get too much variety for a 3-4-5 day trip from Florida. For something a little different, consider the Carnival Victory, out of New York next summer, for 4 of 5 days to Canada. The Victory is a sister to the Triumph & the Destiny. Both very large, spacious, and very nice...
Good Luck
