well, this place called boomers in Newark, Delaware. I think it's shut down but I read it online. It seems like a REALLY good place . Im going to see if its still open today

Don't know about DE either, but check "The Crown" in south Salisbury, MD

Its not in Delaware...but close. Boomers in Avondale is not bad.

There's a laser tag place in the back of Family Fun Galaxy in Middletown. It's $5 per person per round, which is roughly 7 minutes. The course is pretty big, with lots of great hiding spots.
