They WILL allow you to check out your site before booking. During that time of the year, there should be plenty of open spaces. We really like the sites that are beside Middle Lake. I think it's Gator Road. If I could find a map, I could even give you a site # that has a HUGE yard, is right across from the bath house and is just marvelous.
Even though the campground is not ON the beach, you will usually get the breeze coming off the ocean.....therefore, DON'T leave your awning out when you leave. It may not be there when you return. The last time we were there, a quick little storm blew in and the awning on the brand new 5th wheel across from us landed on top of the RV. We were putting ours in when their's went flying or we would have at least attempted to put it down.
You should be able to find lots of things for the kids to do. On Rt 59 heading back toward Foley are several places with gocarts, rides, etc. There are places they would enjoy in Orange Beach, a couple miles down the road and the zoo, though small is fabulous.
Have fun - we will probably take a trip down there during spring break in April.
