the oasis cancun is a building in itself, its a part of the oasis hotels and resorts....its the biggest party spot there is also the oasis playa, oasis rivera maya, oasis viva beach, oasis palm beach, grand oasis cancun.....just to name a few
ahh actually there is 4 buildings as well as the grand building in the middle. I would suggest trying to get a room in phase 1 cus is closest to the party action, we stayed in phase 2 and its not that far away but forgetting stuff for your room and stuff can be a pain ... good luck! tim xx
phase 2 is def. more quiet than phase 1...as for the rooms its sort of luck of the draw, but most are on the same level.
