Trading through RCI - we've stayed at Seawatch a couple of times, and although the units are a little dated, overall it was a great experience. One unit had a lagoon view and the other had an ocean view. In both units, the couch was aligned that you couldn't see out the balcony's sliding glass door, which I thought was weird.
We've also stayed at Royal Dunes, which was nice, but I think that the resort suffered a lot of damage with Hurricane Matthew and it's definitely not ocean front, but not a far walk to the beach.
We have a couple of reservations on HHI through II, and looking forward to those, both at Marriott's so that should be nice.
