Looking for the right destination in December

I am a December baby and I’m trying to find an international destination from the US that I can’t enjoy with some friends and maybe some family members.

Since my birthday is so close to Christmas and New Years, I often run into the problem of having to consider that people may not want to spend a lot of money to go out of the country around that time. But I’ve always longed to go out of the country for my birthday.

I was originally looking at either Cartagena, Colombia or Sint Marteen. However, the plane tickets alone were 1600-2200. I asked a friend if that was too much and they said people probably wouldn’t be willing to pay that. I personally think having this much time to pay for it is enough, but everyone prioritizes differently.

I really want to travel during this time and I want as many people to be able to come.

So, what are some international travel destinations from the US that are more affordable. Here are some things I’m looking for:

Relaxation and fun: I want to be able to relax some days, but go out on a night a few times.

History: I love historical museums and excursions that take me there

All inclusive preferred: it’s not mandatory. I’m willing to book an Airbnb in a place I feel safe as long as I feel like it’s safe. Otherwise, I prefer a resort.
