Don't Trust a Casino Bus
johnsu01 linked to the story that shows what I've been telling people for years: Chinatown buses are dangerous. I really don't believe the Greyhounds are much better. On the Boston/Foxwoods run, I only ever trusted one driver - a nasty, unhappy sort of fellow, but strictly adhered to protocol. Once, he needed to reprimand a passenger for bad behavior and carefully pulled the vehicle over to the side, stood up, walked back, and talked to them, and made sure the situation was handled before going back to driving.
I spent many hours of my life taking shady buses to casinos to go play poker. I'm done with it for life. It's just not worth the risk. I'll wait for the high speed train to AC.
