My Deam Vacation

Hi, we gave up our seats on a flight home from Florida to St. Louis and the airline gave us 2 free roundtrip tickets to anywhere they fly. We would only have to pay for hotels and food, or if a cruise, just the price of the cruise. We are 44 years old and are stuck on deciding where to go and what to do with our free tickets. Tropical Places Air Tran flies: Cancun, Aruba, Bahamas, Jamaica, Miami, Key West, and I think Cabo San Lucas. We only want to spend about 1200 bucks total for 3 nights somewhere. (This would need to include food and hotel/ or the total price for the cruise). We’ve never cruised before so I don’t know if I’d like that or not. We looked into all inclusive places in Cancun that looked great but don’t know which place is best. I checked out Atlantis in the Bahamas but that place seemed overpriced for about 1700 for 3 nights. We heard Jamaica has gone done hill somewhat and crime is a problem, not for sure on that though. Let me know what you’d do and where you’d go if you have traveled to any of these places. Thanks a lot for any information! Sierra
Activities we like to do: lounge around on a beach, sip drink at a tiki hut, look for shells, eat lots of food (seafood, yum!), take a little cruise to see dolphins or to go to a private island, gamble possibly, see a show maybe, but nothing that 20 year olds like, not too wild of partying etc. , more relaxed and secluded beaches preferably. Thanks.
