Looking for Advice on All-Inclusive Destinations

I am a newbie to all-inclusive resorts and am looking for some input
and advice. We have two couples that are looking at spending about a
week at an all-inclusive resort for a vacation this year. We are
thinking of either going in April, or in October, and are kicking
around the idea of heading to Mexico. Specifically, we are two couples
in our early 30's that are looking for good party scenes, activities,
and beaches. I have heard that the Riviera Maya is a neat place, and
may be a good fit for us. We would love to find a spot that would
allow some shopping, hiking, snorkeling, wind-surfing, maybe even some
water-skiing or jet skiing, and a great night life. Any ideas and input
anyone could provide would be greatly appreciated.
