Just in general, if you decide you like the East Coast beaches/pools/amenities/activities, etc, particularly as found at the Marriotts
(Myrtle Beach's Oceanwatch, Hilton Head's Grande Ocean, Barony, or Surfwatch) then absolutely purchase a resale deeded week.
You won't regret it, and you'll have a FAR easier time booking what you want year after year.
And if you REALLY want an advantage, buy TWO weeks to take advantage of the 13 month booking.
You'll enjoy a lifetime of memories, and buying a resale week pretty much assures you of recouping your money if you ever sell (just a mental plus),
as resale prices do not immediately drop as the ink dries on the transaction as it does buying directly from Marriott, but instead stays fairly steady.
We own at Oceanwatch, Grande Ocean, and Barony (see left column here), and we have enjoyed our own "paradise" for a long time and will continue to.
Matter of fact our whole family and very young grandkids are here at Grande Ocean now (2 birthdays this week)-----
My oceanfront living room's screen window is open so I can hear the ocean (and the sound of the waves are loud!),
and I'm literally smelling the bacon right now and sipping my coffee,
all the while alternating between watching the French Open tennis on TV and seeing the dolphins play just offshore.
Somebody please pinch me, this can't be real.
