If you can get a direct flight, Savannah. If it takes a connection to get there, check out Jacksonville and Charleston for a direct flight (each 2-3 hrs) from HH. If nothing direct there you can even check out Atlanta and Charlotte which are both about 4 hours from HH and likely to have direct flights. I know 2-4 hours may seem like a lot, but since there aren't many direct flights to Savannah (which is still 1 hour from HH), the hassle and time it takes to make a connection (while taking on additional delay risks) make a direct flight to an airport further away potentially easier and faster.
