Yup. Birthday suits are required for all guests on the island, regardless of whether or not it is your birthday. The only exception is the bartender (While I am sure he has a birthday, he does not join the brithday suit island fashion trend).
Yep. I believe you wear clothes on your trip to the island via boat, then you venture to your "spot"... disrobe and relax. If you are going to the right once you get there, I have been informed that is the more private/secluded area, and if you go left, you will get to the pool and swim up bar.. but you would go to your location probably and then disrobe. If I'm wrong, let me know, I don't want to break protocol, I leave in 22 days!!!
I also am assuming that I will have to go to the bar to get drinks, even if I am hanging out on the lounge chairs on the right side?
MrH, the only way to get there is by boat unless you want to make the swim in the dark. I have seen some people swim out in the morning. The resort goes dark early enough to allow for stargazing right on the main beach if I remember correctly. 34 more days for us!!
