St Andrews State Park, Florida

Has anyone stayed at St Andrews State Park. We will be staying there this weekend for Thunder Beach (Fall). Are the spots "big" as compared to the length stated on the website? I know some say 35' or 50'. We were hoping to keep our enclosed trailer on the campsite with us and use it as a garage for the bikes at night. Our trailer is 16' and our Class C is 31'. I called the state park and he stated that we could keep the trailer on site if everything fits in the site. They do have a trailer area but we would like to keep at camp if possible.

Any comments are appreciated.
