Hi Kim.
We're from PA also and looking for a break from the snow and cold. We just got the MH out of storage today
to get ready for a two week trip to Hilton Head Island, SC. We were thinking about Myrtle Beach but decided to go a bit further south to gain a little more warmth
You can make Myrtle Beach in a day if you don't mind a long driving day. We're going to take two days for Hilton Head.
My recommendation ... don't ever lose any vacation time, just add another two or four days to the 5 days and relax
cheers,
Joopy
