I love Aruba! One thing to consider for the caribbean is hurrican season. I don't know what time of year you're considering going, but be aware of that.
Aruba is outside the hurrican belt. Also, they get very little rain (a big concern for me - I don't want to put the money into a vacation and have it rain even though you can predict the weather, but knowing your chances of having beautiful weather is a big plus

). The temp is around 84-86 daily, with warm tropical breezes. You can rent a 4x4 and go off roading!- they have great restaurants and delicious water (don't have to worry about drinking the water here - it's some the purist water you'll find). Just some things that are important to me - might be something for you to consider - oh and you can go thru customs right on the island!
