RIU Merengue???

Question

I'm going to the RIU Merengue On Feb 22, 08. everything is booked and paid for. I'm so exicted, but I'm worried about getting to the airport in DR. what do I do when I get there? tere is supposed to be a bus or something to take us to the resort...how do I find it? they said something about hotel reps getting you on the bus and stuff. how do I find them or where do I find them? I'm so worried I'll be stuck at the air port or something. help! I've never travelled before.
