All-Inclusive trips to Mexico! Please help:)?

We have a group around 10-20ppl and I need help deciding on an all inclusive hotel.airfare/food/alcohol.. We are a young group 18-26 so we would like it to be somewhere where lots ppl our age will be there and the bars only a short distance away. I checked out a few hotels already like the oasis plam beach in cancun, NH Krystal in Cancun and the Crown Paradise Club in Cancun.....Not sure which one is the best our if any...so if you guys could help me decide that would be great!
