NYC or Disney World for anniversary trip in December? Other suggestions welcome!

My partner and I (both in our mid twenties) are wanting to plan a 7 day trip for December 2026. Budget would be around 6k for everything including airfare and lodging. No kids, just us two. We’re not big party people. We like outdoor activities, but we also enjoy being in the city. Right now I only have two rough ideas: NYC or Disney World in Florida. If we go to Disney World we would only be there for 4 days because I’d like to stay at a resort and that would use up a good chunk of our budget. If you have any other ideas for a December anniversary trip I’d really appreciate your input! In the U.S. only please.
