As a previous 'camper' stated, it's a great place to stay if you are seeing a show and don't want to get stuck in traffic or drive home. A shuttle bus goes thru every 10 to 15 minutes 24/7. A parking pass is issued free of charge, just for security sake. Apparently issues of people dumping down sewer drains. Granted no shade. But if you get there early enough you can get a 'river view'. We camped here in a Motorhome.
There is no cost for staying here, but you must put in a dollar amount. This is not a campground, but the casino has a large blacktop parking area set aside for RVs. You have to call for a permit and security gives you a pass good for seven days dry camping! When we were there it was packed with approximately 30-50 RVs. They have a shuttle service from this lot to the casino. We camped here in a Motorhome.
