While it's always nice to leave the kids at home and get away with your partner (or, heck, leave your spouse behind and travel solo), there are few things better than a good old fashioned family road trip. It's a time honored tradition as American as apple pie. (Also classic: the inevitable choruses of, “Are we there yet?”). These budget-friendly family road trips traverse the country, with sights guaranteed to please all ages, so your kids will remember this vacation long after they're grown.
