Planning 25 anniversary trip. We want a resort setting. WHAT CARIBBEAN ISLAND, AND WHY? What makes it so special?

You left out important information like when you want to do this. And what are you looking to get out of the resort. You looking for quiet and romantic or upbeat and fun?

but Generally, there's Jamaica, Dominican Republic and Mexico. I name these 3 as they all have several no kids resorts which is probably what you are looking for.

St. Maarten. Beaches all around.

The Virgin Islands, either the American side or the British side. I've been to both and prefer the British side.

Anguilla - it is a secluded paradise. You won't find large amount of people which means you won't find large groups of obnoxious idiots. The beaches are relatively empty and the food is excellent.

However, if you want large groups of people St. Maarten is fun (Anguilla is just a ferry ride from St. Maarten, so you could do both very easily)

Don’t go to any Carribean island. They all smell like stinky dark people
