Topsail Island, NC (south of the Outer Banks). Oh my, it's just beautiful. There are souvenir shops and restaurants, and other than that, nothing to do but play in the surf and soak up the sun. The beaches are marvelously un-crowded, we usually have it to ourselves! Pretty much the opposite of a go-go-go Disney vacation. This is where we go to relax!
As far as budget, you can get a house on or near the beach in pretty much every price range. We usually rent an oceanfront house that's about $3,000-$4,000 a week that sleeps 10-12. We go with my sis's family and my dad/stepmom and split the cost 3 ways. We usually only eat out once or twice, and all go grocery shopping together for the week. Each family takes turns making dinners. We also drive from Ohio, which (I think) takes 9 or 10 hours. It turns out to be a cheaper vaca for us than Disney, and it's nice to have the quality time with family members we don't see that often.
We LOVE our
Disney vacations, but also LOVE our Topsail ones!!
