Studios and 1BR's at Hilton Head are scarce and very hard to get inside the 7 month window. I got the last studio for a July date in 2003 at exactly (to the minute, LOL) the seven month window. A 1BR never did open up for us off the waiting list. But, it is worth the try. What a great resort. We bought an add-on to make sure we could get a studio when we wanted one in the spring or summer.
