We stayed at Cocopah Resort and it was a good place as long as you follow all the rules. God help you if you go the wrong way on their one way streets even if it is only 3 sites in.
My son lives in Tucson and said .Why go to Yuma. We said the same thing at the casinos.Why do we go we never win, a Canadian said. We said there little else to do. LOL
We've gone across the border there and they treat you far different then in Texas. Heck they even limit the booze you can bring in there.
We've stayed in several places in Az and think Casa Grande was about the best all around spot. About an hour + to Tucson. We also liked Tombstone area.
We tend to stay at several spots across the US in Winter all have something good and many have to many bads ie: Quartzville to us sucks, really sucks unless you are going for survival.
