We are a group in our late 30s and we want and AI with a great beach and entertainment to relax for 3 days before we head to an apartment we are renting. We want the AI to have a great beach, pools, service, and good entertainment so that we don't have to leave the resort. Mid-range price is fine. I was looking at Riu Cancun but the beach looks really bad and I feel that maybe some of the entertainment is outside of the resort? Could be wrong....but any other suggestions welcome. We plan to head to Chichen Itza the last day and then head to an apartment we are renting in playa del Carmen. We all arrive into cancun...so I thought something nearby would be great. I haven't been able to find too much info on AIs, maps, entertainment etc. Suggestions welcome!
