Planning a weekend trip around escape rooms

There are a group of us that have been doing escape rooms together a couple of times a year and we are considering going somewhere and just spending a weekend doing them. Figure probably 3 or 4 rooms a day for two days.

We would be coming from in between New York City and DC and would probably like to keep it relatively close just to keep travel costs down a bit. Within driving distance would be preferred, but flights aren't out of the question.

We do all have our passports and have Quebec on our list, but are there others we should consider?
