From my part of town.
Actually there are a couple of really nice spots depending on what you want to spend.
North and South Carolina: There is always Myrtle Beach, which I love because there is a TON of stuff to do there. The beaches aren't bad, not the best, but not bad. There is always Nags Head which I hear is wonderful beaches and a really nice spot.
In Maryland there is Ocean City. I grew up in Maryland, so we used to go there all the time. I like the beaches there more than Myrtle, but there is more "other" stuff to do in Myrtle.
Cape Cod is wonderful!!! Provincetown, MA - there is whale watching there. Awesome spot for a vacation. Right on the water, very beautiful.
Those are a few that I know of. Hope this helps.
