I'm a last minute planner and was thinking of taking a long weekend at Hilton Head with our 4 kids -11, 9, 6 and infant. I just realized my time off is also 4th of July weekend. Arriving Wed July 2-Sunday July 6. Availability will probably be scarce. Any good places to start to look for hotels or suites that can accomodate our family? Or best locations on the island for a VRBO with activities for my kids under 12? Thanks!!
