Bob-
Good choice! Great vacation spot, great sailing! Broke in my Wave there in 2006 for two weeks, did the same in 2007 and 2008, and already waiting for next summer. I loved every minute!
My experience for OBX has been Hatteras Island, ocean side from Cape Point down to Hatteras Inlet. Haven't done the soundside yet or beyond the inlet to Ocracoke Island, but it's just a matter of time. Can't speak for the northern beaches.
Re: Beach driving, you'll find a lot of opinions, so I'd recommend you do your research, listen to the opinions, and make your call. I've towed my trailer onto the beach once with my 4x4 pickup, off of Ramp 55, but I've got relatively zero beach driving experience and found it easier and quicker to use the cattrax and roll her over the beach vice driving on the beach with the trailer. Also didn't want to chance impacting my time sailing (I'll correct that when I move there and refine my beach driving skills and add wider profile tires for the trailer). Not sure how a Getaway would compare to Wave. I've done the drill singlehanded and with the wife, but there always seemed to be volunteers to willing to help.
I've launched from several locations (ocean side) where the beach roll is ~50-200 yards, relatively level, in moderate to soft sand. Some examples:
-Parking lot near beach access ramp immediately north of Cape Point (Ramp 43 I think),
-Frisco Pier parking lot (shortest thus far),
-Top of Ramp 55 access road
-Haven't used any yet, but there are several soundside access points too.
We rented an oceanside house, launched from one of those sites on our first day, and sailed to the beach near the house. Sailed the dogcrap out of her during the day and left her on the beach overnight (less sail, rudders, and gear) and had no issues, save some sandy footprints on the tramp. Great place to watch the stars at night, and possibly other nocturnal activity. Keep in mind high tide, high wind, and plan appropriately. Watch the forecast as departure day approaches (no wind mean no sail).
If you decide to launch and recover daily, there will be some days when the sound will be better (good winds, less waves).
Use Google earth and the Dare County GIS site to scope out in advance, then follow up with some with recon, while you're down there on vacation.
You'll find a lot of good gouge on the following sites:
