i went on a disney cruise with my cousin for graduation and i wish we had gone to hawaii instead for sure. didn't occur to us that we would be the only early 20-somethings traveling by ourselves. people kept asking where our kids were. my cousin is very beautiful, and creepy older guys kept sending her drinks while we were relaxing by the pool, at
castaway cay one day a guy followed her around trying to flirt - his daughter was only a few years younger than us!

we loved, loved loved castaway cay - it was beautiful - but didn't like nassau and were bored on the days spent entirely on the ship. i wish i had just gone to WDW for a week instead of doing WDW for 3 days and the cruise for 4. it's great if you are traveling with a family and i'm sure it would be romantic if you are going with a significant other, but didn't work for me.
