It's about a 30 minute drive to Philadelphia where you can check out historic Old City, run the steps of the Philadelphia Art Museum or grab a cocktail in Rittenhouse Square. Don't forget to try a cheesesteak! (We suggest splitting one to feel lighter on the dance floor)
If you want to stick to the suburbs, you could go for a walk in Valley Forge National Park or explore the small towns of the Main Line and all the shopping it has to offer!
