What is the most ideal location for 4 21 year old males to travel to in the Caribbean or Mexico?

A group of friends looking for a nice all-inclusive resort for a week long vacation in May or June. Want to have a good time, but under control. Where would you recommend we travel? Aruba, Cancun, Bahahmas, Bermuda, Dominican Republic, Puerto Rico...those are the places we're considering but any other recommendations are welcome. Other than recommendations of the best destination we'd also like insight on where any normal 21 year old would enjoy.

Aruba on course! You'll have lots of fun there.

Sosua-Cabarete, Puerto Plata, DR.
Nice beaches, water sports, nightlife, excursions, restaurants, good Resorts/Hotels, international cuisine, Golf clubs etc, etc. many activities for you to do and not get bored.

Good luck!!
Enjoy your trip!!

Cancun is the place to go if your young. It has the most to do.

I might suggest the US Virgin Islands, cause...

...drinking age is 18 (though you probably don't have to worry about that).

...you don't need a passport to get here.

...transportation is easy.

...rum cost $4 per liter (though milk is $8 per gallon...guess what I put on my Cheerios).

...and, it's the freakin' Virgin Islands!

I live on St. Thomas, but I would suggest St. John... especially during the first week in July (that's when they have their week-long Carnival celebration).

Head for Curacao. Can't explain why on this site. Why an all-inclusive? If the women aren't there, you're stuck at some resort that you don't like. If you've been overseas before, get brave and head for a villa where you can make your own parties (Negril, Jamaica is the spot).
