And the best all-inclusive resort is...?

[ASTalumna06]

I need help! I'm turning 30 in January, and my family will be going on vacation. We definitely want to go to an all-inclusive resort. It's ultimately my decision as to where we go... but I don't know!

We'll probably have about 12 people going - my bf, parents, brothers, aunt and uncle, and 2 of my cousins and their spouses. We range in ages from late-20s to late-60s. I know that may sound as though it'll be hard keeping everyone happy with such big differences in age, but my aunt and uncle, who are the oldest, sometimes party harder than the rest of us!

Because we'll all be flying from different places (NJ, MD, FL, and TX), and so as not to require anyone to have long layovers and travel times, Mexico (Playa del Carmen or Cancun) or Jamaica seem like our best options, but I'm open to other places assuming the flight times/prices work for everyone.

To make everyone happy, I'm looking for all of these things below, but I also understand that to get all of this in one all-inclusive might prove difficult:

- adults-only - but it wouldn't be the end of the world if it wasn't, as long as the place isn't overrun with kids
- restaurants/bars/a resort that's "open" late - I know that most of us won't want to be back in our rooms and asleep by 10:30.. but we also don't want it to be party central, either
- a decent number of food options
- a big/long beach - my parents and brother especially enjoy taking long walks on the beach
- good service! I'm usually willing to ignore some of the shortcomings of a resort if the staff is friendly and helpful
- and I'm pretty sure my family might disown me if the place doesn't have a swim-up bar!

Are there any places that you all would suggest?
