Beautiful place to renew wedding vows?

My husband and I are looking for a place to renew our vows next summer 2012. We are bringing our children also (next year they will be 1 and 3yrs old) .. Somewhere close to PA or Delaware beaches? We will be driving and live around Lancaster, PA.. will drive far if its the right spot! It will be just us and our kids so something slightly romantic but more just beautiful scenery! If anyone can help please do! Thanks :)
