Need to get away - please don't move

Looking to get away this summer for just a couple of days with the kids (boys 7 and 5).

DH and I spent a lot on our backyard and threw two big parties that we realized the summer is coming to an end and didn't get a chance to get away. We have friends going to the outer banks or Rehoboth.

Maybe Hershey, but that's really a one night trip.
Any other ideas to get away that won't cost a fortune? Worth going to Hershey one day then Dutch Wonderland the next?

Thanks!

Re: Need to get away - please don't move

We went to Philly for 2 days. We did the Please Touch museum, Franklin Institute, Aquarium and Liberty Bell (DS#1 had really wanted to go there - was slightly less impressed than he expected. )
We also decide to take a Duck Tour which DS#1 seemed to like until he realized we were going into the water. He freaked a little but once he found out we weren't going to be getting soaked, he thought it was great. DS#2 fell asleep (he's 3.)
I didn't know there was a dinosaur museum there or we probably would have done that. We walked past it where they had animatronic dinosaurs which both kids thought were awesome!
