As soon as we arrived, we were told by security that there was no overnight parking at Wal-Mart in Clermont, FL on Route 27 on March 23, 2006. There were no signs posted and several other RVers were taken by surprise also. He was very nice and suggested that we write a letter to complain. I would not complain about a courtesy that most Wal-Marts extend to us, but this one should post signs.
