We'll be taking the BIG travel trailer for the first time and will be stopping along the way before checking into Fort Wilderness. Have you ever stayed in a Wal-mart parking lot overnight ? I've heard that it's fine with the management across the nation and even welcomed. Do you know if there are restrictions or requirements to park there ? Is it safe ? Other than not having hook- ups, are there any disadvantages to doing this ? Any advice you could give is greatly appreciated! Thank you! Mitzi
