It's that time of year again. Looking for recommendations for nice places to stay in Mexico. Last summer we took a ladies trip (mom, sister, and two family friends) and stayed at the Riu Palace in Riviera Maya. We had a great time at the pool bar and laying on the beautiful beach with the Caribbean waters. This summer we are looking for something with a little more to do after the sun goes down and the pools close. The family friends will be taking their families, so we will have four teenagers that will need to be entertained for 4-5 days. We had looked at the Moon Palace in Cancun, but read some reviews that the beach isn't nice and the water isn't anything like the water at Playa del Carmen. Any recommendations anyone has would be great!
