Hello, We have been to VB with our RV many times. We always stay at First Landing State Park. The airplane noise can be loud at times but it wouldn't be a deciding factor for me in terms of staying there. We love FLSP. Love camping in the dunes. We also like the dedicated bike path that runs along the waterfront at Virginia Beach itself.
We have only been once to the Outer Banks. It is beautiful there. We stayed at Camp Hatteras. It was in April so not crowded at all. We stayed on the bayside to watch the sunset each night.
Have fun whichever you choose.
