Need some advice. Travelled to Cancun last fall and loved it...except that my husband would like to be able to snorkle right at the hotel anytime he wants without have to plan an excursion. We are looking at another fall trip and thought we would try Cozumel. We will be with another couple and definately want all inclusive and a place that has entertainment.....fun....nightly stuff. We are early 40's but enjoy cocktails and music. So....anyone know of a place that has all of these things???
