we have gone on charters with tnt and gwv. they provide an orientation the following morning after you arrive there. if you are on one of these charters, you can book all your excursions right then and there because all the people who run them are there that day. they also have raffle tickets when you enter the door to win free prizes like a jeep tour, sunset cruise, etc. they also give you a 10percent discount on a lot of the excursions. bring your money with you when you go and you can plan your whole week. it saves lots of time and it is well worth approx. 1-1/2 hours of your time. believe me, it will take you more time to do this all on your own. have a great time. your son will absolutely love it. going again for our 8th time in april and cant wait.
