LA, you have gotten some great tips from some very seasoned travelers. But I will agree with skipdastraw's last post. It is completely up to you how much you want to endure on your last day of vacation. We have done our last day on STT as well as the scramble to get to the airport on time just to have a few more hours on the island. After many years of doing both, once on the plane we chuckle and agree it was all worth it. Whatever you decide, you will have a great time. Enjoy!
