Ok, I priced Del Coronado for a week in June- $3400 with tax for a non view Queen-Queen room. If this is your price range, you can easily afford a resort home in the Outer Banks, maybe not oceanfront but for sure on the sound within and easy walk to the beach on Hatteras Island. We rent a 3 bdrm condo sometimes right on the sound overlooking sunset and a kite surfing school(great show in the afternoon!). It's about 2200 for the week with 2 full baths, three bedrooms, private hot tub on the balcony and a great pool with a gazebo that has direct sound access for swimming if the surf beach is too much for you. Literally a 5 minute walk over a low dune to an excellent, wide and as far as you can see beach near a fishing pier and good surfing. PM me and I'll tell you exactly how to book that. Seriously, I've been to La Jolla, San Diego, and a few other beaches in that area so I know where you are coming from. Hatteras is not nearly as developed which is why the whole state of Ohio goes there in the summer but the beaches rock. There are several surfer stores, board rentals, bike rentals...and two Dairy Queens plus myriad of other private, small snak business on the island which is about 30 miles long. Kayaking, National Parks programs(the islands are 70%NP), kite surfing, parasailing, world class fishing and amazing freshly caught seafood are among the things offered on Hatteras. Also, within about an hour's drive is Roanoke Island and the Kitty Hawk Wright Brothers museum and launch site. We take a ferry to Ocracoke when we go down and find the most amazing, deserted beaches there as well as a very quaint town with good food, sweet shops, bike and cart rental. From Kitty Hawk to Ocracoke, there are four very famouse and interesting lighthouses, the Hatteras Lighthouse can be climbed. This IS one of the best family vacation spots in the world!
I've been to Hilton Head. The beach is hard there-you can bike on it. I also thought it quite expensive as far as shops and restaurants go with little choice but lots and lots of man made scapes compared with the natural beauty of Hatteras and Ocracoke where you can still find an occasional sand dollar or ancient sharks tooth just lying at your feet in the surf and national surfing competitions.
