Recommended Caribbean vacation: Casa de Campo in the Dominican Republic.
Get several couples together and get an AirBNB villa big enough for all of you.
We're coming up on a year since we went there with my siblings/spouses and my parents, and I'm desperate to get back. If you go as a group, it'll cost about the same as a nice hotel, except you get a giant house with a private pool and personal staff in one of the nicest communities in all of the Caribbean. I do recommend paying for a personal chef (a bit extra each day, but not too bad) so you don't have to worry about food.
If you golf, Teeth of the Dog is one of the best courses in the Caribbean, although it will cost a pretty penny (we did not golf, but we did take pictures on the golf course so we can pretend like we did).
