My neighbors just opened Jump-N-Jimmy's bounce place. Check out their website for info, photos and hours. We've been there several times and it is really nice (and new). There is a parent area with a tv and wi-fi. It is unlimited bounce so you could stay all day if you're up for it. It's great to have a place like this without going all the way to Manassas!
Give it a whirl over Christmas vacation and tell your friends!
