Hello -- my family of 6 is headed to Chincoteague for the Memorial Day weekend. I haven't been in a very long time, so am wondering if it is going to be very crowded. I'm certainly expecting more folks than usual, but for example, should I book things like a nature cruise or bikes in advance? With teens, I generally like to wing it, but am thinking I might need to do advance planning! (We do have hotel reservations!) Thanks.
