Overnight RV Parking is OK - 7 day limit
Desert Diamond Casino I-19
RV Parking and Camping Information
We stopped for a quick overnight here. It's very convenient , right off of I-19 at exit 80, but this makes it a little noisy because it's so close to the interstate. To get to the RV parking make the first left after turning into the casino driveway. The parking area is very big , making a semi circle around the casino. Security uses bicycles and would like you to check in with them so that they can take your information and give you a copy of the rules. Don't worry if you can't find them - they'll catch you at your motorhome eventually.
We went into the casino for a few hours. It's fairly new and nicely designed but it seemed to have pretty bad paybacks. All of Arizona's casinos are owned by Indian tribes and aren't required to post the payback percentages, so we can only go by our very short experience. See photo of parking area.
Desert Diamond Casino on highway 19 just south of Tucson, Arizona, allows up to seven nights (free) parking using basic, commonsense rules about what to, and not to do behavior.
This is a five star casino with a beautiful convention center that also offers top rated entertainers, boxing and four outstanding restaurants all with reasonable prices. The slots seem to payout on a regular basis as well. While we were there we counted as many as 15 RVs parked there overnight.
