I visited the Primm resorts 2 times for a day trip in over 20 years of trips to vegas. It's a one time thing for most steady vegas tourists at best on average.
For locals, I don't see a draw, unless you like long drives for basically nothing. The roller coaster is nice, one time, but I don't see the attraction.
California tourists, why stop here except for a restroom break? With the casinos closer to them, with all the indian gaming, I don't see the lure here they once had. It's plain to see they are having trouble filling the places, when they offer room rates at under $20.
I have always thought of Terribles as a locals joint. But without any real draw. Cheap food, ain't going to cut it, it's got to be good too. Service has always been lacking as well. I know, I've quit stopping there a few years ago. Too many better places to spend my money IMHO.
If I recall correctly, didn't the old Continental have the same trouble drawing locals too???
