Looking for ran adult only AI resort in the Playa mujeres/riveria maya location. My husband and I are in our early 40's (dont feel like it). Looking for a resort that isn't huge, like a mega resort. Although we love the relaxing on the beach/pool I have a short attention span and need things to keep busy (volleyball or other activities). We don't want dead. Something that has things going on especially at night. We are looking to go next Oct. 2013.
