I never stayed there, but regularly took advantage of a promotion for players where you paid $2-3 to register for a program that gave you free chips, and slot play, given in pieces after 15-25 minute increments. You had to go back to the promotions booth within 5 minutes +/- of that increment to get the next reward, and the old ladies in the booth enforced those times like their lives depended on it. We had it timed so that we would walk over to IHOP for breakfast during the longest increment of the program, so the 2 or so hours of hanging around wasn't really that imposing. It was a average $25 profit for each of us every time, and the only risk was the $2-3 registration fee.
They had that one in all the freebie magazines (remember the 3 minute free long distance call at Lady Luck?).
You really had to be a cheap asshole to wait around 2+ hours to grind out about $20....yeah I hit it a couple of times.
