Good solo trip close by?

I need a 2-3 day solo vacation by myself where I can disconnect completely and just relax. I know it’s winter , I hate the cold. But I don’t want to go too far from Maryland. Maybe somewhere I can relax in a hot tub at an Airbnb. Peace and quiet. But also have the option to go clubbing / dancing one night (I don’t mind going alone). And maybe go to a nice spa or get a massage. Any ideas? Thank you!
