What part of the NC coast? I'm a diehard OBXer seeing as I vacationed summers there since I was 12 (34 years in the same rental house too). My sister and I still go every year.
Sunset Beach, Ocean Isle area, love it and best part is over the border to the SC side is a very short drive for the few things that we enjoy with the hustle and bustle. We are a few minutes from OIB, I love it, also have a boat that we launch at Ocean Isle take the intracoastal to the Shallotte inlet area, gosh the water there last August was Caribbean like, turquoise. I couldn't believe it, will find out this year if it's always like that. Ran out the inlet for the first time there. We only got the boat from our storage place at our SC home mid august last year.
Before moving here for at least 5 days every summer we would stay at Sea Watch, N Myrtle Beach border with Myrtle Beach. It was always our mini carefree low cost get away vacation without fail and then another main vacation other places, be it the mountains or various places in Florida or all three.

More times then not, all three spread out over the summer.
It was a great way to chill and enjoy the summers. I guess I have never been much of a traveler in the sense of overseas vacations. Most I ever did was the islands a few times.
So last run of the year last year I took my dog and wife out Shallotte Inlet so they can experience a short run into the Ocean. My wife and dog previously only experienced the lake. It's a tricky but fun inlet. If I could post a video I would have, pretty wild with waves breaking on both sides between the somewhat narrow channel.
Photo shows the OIB water tower in the distance as we were heading back in.
The other photo shows the bulkhead and flag pole of the Inlet View Restaurant. You can see the incredible clean water in the boat engines wake. I don think it's like this year round but just the fact that it happens is awesome. I suspect it depends on incoming or outgoing tide from the intracoastal. Which would make sense.
