Parking lot is large and there is plenty of room as long as you leave a space between you and others. Otherwise its a tight turn to get out of your slot. We usually cheat by taking two slots as we put out two slides. The lot is west of the parking structure and that provides the only shade. The games are friendly and the food is very good. This is our new stop when heading around Chicago.
I spent 2 nights at the Four Winds Casino and Spa 7/02-7/03/10. Travel to the oversized parking lot is well signed, and located adjacent to the parking garage. The walk to the casino is through the garage, cool in the summer and dry in the rain. The lot is asphalt, level, well lit, and frequently patrolled by security.
Stayed on 8/2/08 RV's are required to stay in parking spaces along with buses and trucks. Spaces are behind parking garage but not too far from casino.
The parking slots are short and narrow. Too short for trucks and so narrow that a truck has a difficult time getting in if there is another truck in the next slot.
There was plenty of space in both the regular parking area and in the employees area so I don't understand the thinking here. Not so bad to have to park in designated slots but spend all night next to a running truck is not good. If they would provide a trucking area a good distance from the RV's, it would be OK.
