Cayman Islands
Costa Rica
Puerto Rico

Puerto Rico!!!!

Barbados is the place for you to visit. There's lots to do here (yes i'm a proud Bajan i.e. Barbadian) and we have the following attractions if, as you say, you love to party...

St. Lawrence Gap - http://www.barbados.org/stlaw.htm

Time Out at the Gap is where many Jazz entertainers choose to stay and to play and you will find some of the best names in Jazz playing right here.

Reggae Lounge - this open-air nightclub offers the opportunity to dance the night away under the stars, surrounded by natural, tropical vegetation. The club offers a wide range of music, from reggae and calypso to mellow music and Rhythm and Blues.

The Ship Inn, proclaimed as "The Original Pub" has a DJ several nights of the week, along with live bands.

For lots more... (see links)

I am a Trinidadian (Trinidad and Tobago) myself and if you wanted to have that type of fun (partying) I could advise you to come to Trinidad during the first quarter of the year (the Monday and Tuesday prior to Ash Wednesday to be precise) to experience our carnival. Nothing in the whole of the Caribbean (or the world for that matter) compares to Trinidad Carnival. However, that time has passed for this year, but if you plan to tavel next year as well, this is the place. The parties start officially after New Year's and go right through until Ash Wednesday. Try it next year.

Cancun, Mexico
St Maarten/St Martin

Definitely Barbados...
Lots to do, its a cool relaxing atmosphere.
Most 20yrs party in a club called Club Xtreme its usually lots of fun there is also a place called (Boatyard)or Taboo i think and I'm sure you'll discover lots of other places and things to do here.

If you coming in the summer especially its our Crop Over festivities and there is lots of places to party.

BARBADOS OR TRINIDAD

if you want to party in the evenings and cool out during the day on some nice beaches then maybe you should try negril, jamaica!

Here's a new suggestion. ANTIGUA. I don't think anywhere in the Caribbean parties like Antigua. Lots of clubs like Rush, Abra Cadabras (think you would like this one), and Coast to name a few. Great night life especially in the summer. Look it up.
