I enjoy Laughlin a day or two at a time. Stayed there a week once, and that was too long.
As far as taking the bus down and staying overnite, it's not allowed, but talk to the person who greets the bus. I did and the next day he spoke to a driver with less than a full load and I got a ride. Surprisingly, neither the greeter or the driver would accept the $5 Bill I offered them. When we got to Vegas, I noticed others tipping him so that's what I did. They are pretty strict on no luggage so travel light.
One peeve- I was staying at Harrahs and had a 745 pickup. We were the first ones on the bus and went to a couple of hotels before returning to the Imperial Palace for their scheduled 830 pickup. The walk to the pickup area of the IP was the same as the Harrahs pickup and would have savex45 minutes of driving around casino parking lots.
