We tend to take the ratings at face value. Their ratings weren't 9s or 10s but they were high enough for me not to be immediately concerned. But we were knocked over like the OP. We were going to camp at a place in Yorkville IL Hide Away Lakes for the 4th. They said no reservations needed just show up. I was leery, but did not have time to investigate further. Since this place was closer we finally took a ride out to see it.
To quote"This is the worst possible dump" but it was in a great location. This place was a cross between an abandoned trailer park, junk yard and trash dump. There was abandoned trailers with trees growing through and around. There was abandoned trucks from some tree service. There was a 'pool' the 6 people in it were all holding beers and swimming. (which is fine except when you try to say you are family oriented camping)
Good Sam Rating - 7.0 4.5 6.0. We never got out and left. Can I add to this rating? There is no way that it deserves a 7 for facility and 6 for appeal!! I will not comment on the bathroom because I never checked, though I doubt it would be worthy of even the 4.5
Needless to say we were to close to book any other place and hence are staying home this upcoming weekend. So I got screwed out of a camping weekend.
