Hi Lindabobhat:
The fountain is on the green of the Villages of South Walton, which is just 1 mile east of our cottages. Our kids will love the fountain when they see it. We find that there is plenty for us to do on our side of 30A now with Fonville Press (lovely coffee shop with very nice courtyard with free wireless access if you bring a laptop -- also great place to sit and read a book -- there are also after beach wine and appetizers on Friday and Saturday nights and I'll attend my first one on May 6) just 1/2 mile (an easy walk) from the cottage and it tends to be quiet early in the morning if you have any early risers who want to take a walk. Then there's the Villages of South Walton 1 mile away with the fountain, Seacrest cafe (sandwiches and other meals, as well as great Carvel Ice cream and desserts with plenty of seating inside and outside), and some shops and kiosks. Then there's Rosemary Beach right after Villages of South walton with shops, restaurants and an outdoor craft market about every other weekend in the summer (we like to get ice cream and then go to the fountain at Rosemary Beach that you can turn on and off -- the kids love that fountain although I don't know the exact street name at Rosemary Beach -- perhaps someone else on this board knows the address of that fountain). Then there's Shades by the Loop with useful wireless Internet access and great oyster po'boy sandwiches. All of these places are easy for families.
When we want to venture off the east end of 30A, we go west to Seagrove (4 miles) for Angelinas, Seaside (6 miles), Grayton State Park (9 miles and well worth the trip), and Grayton Beach (10 miles).
