This is my favorite KC-area casino. I get the sense that the Harrah's crowd is slightly more upscale than the Argosy or Isle of Capri crowd. Not that any of these riverboats draw the James Bond set, but the "redneck factor" seems a tad higher at the other places. Again, not that I have any problem with the 'necks...
Harrah's game are, for the most part, a little tighter than they are at the Argosy or Isle of Capri. Although Harrah's used to advertise 10x craps, I haven't seen anything other than double odds in a while. Some dealers will let you go triple odds on the six and eight; some won't. I can't figure out exactly when they will or will not allow this. Blackjack is always dealt from a six-deck shoe, and the rules seem to be typical of an LV strip casino (i.e., on the tight side). Still, this is a fun place to go, and the restaurants/bar are pretty good.
I believe that Harrah's still has a live poker room on one of their two boats. There's also a hotel attached to the casino, although I've never stayed there.
