They bring you (for a fee, of course) those little drinks with umbrellas, tone of lounge chairs, you can rent snorkel gear if you want. When we went (several years ago) they had a huge BBQ lunch under a pavillion. We did parasailing there and it was absolutely beautiful. Now they have the zipline ($65, I heard) there are pictures of it on one of the threads somewhere.
Labadee, part of Haiti is fenced off from the general population...so coming and going to the ship there were a few people on the other side of the fence asking for money. Other than that it was exclusive to the only people who got off that RCL ship. They also had a hand full of locals selling their wears in a small building!
Beautiful country and a great start to our cruise!
