Here is a map with the Coco hotel room numbers - http://keithpaul.net/2011/01/cocolapalm-map/

I believe they would make your friends check in and the patio areas vary on privacy, but overall a nice place and we had no problem chatting with and getting things from the vendors on the beach while we were there. If you go through negrilonestop.com you get a free breakfast. Close to Sunbeach (we went over there for a day) and in the middle of everything.
