WARNING WARNING WARNING stay a way from Wild West its a dump, its also tied into a truckstop. Stay away from the old downtown at least don't go off fremont experience, bums, druggies, con artist, and strippers. That came from security at Nellis.
If you want to gamble stay off the strip, although the slots are random the strips are setup to not pay out. That came from a guy who programs the slots.
Palace Station (or any of the Station Casinos)just of the strip, it caters to locals so the price is fair. Plus they have truck parking with security. We stayed there a couple weeks ago for the 3rd time it was $48. I think its Boulder Station that has a theater and bowling alley.
It appears you have wireless internet or at least a form of internet, try Hotels.com, they have some good rates and you can book a room then check in right away. Expedia and Priceline have somewhat the same rates.
If you have a few days check out the free stuff on the strip, like the violcano, and aquarium at the Mirage, Flamingo's bird sanctuary, the gondolas at the Venetian. Check your Event Magazine in your Motel room, lot of free stuff going on.
I think the best Buffet is out at the Silverton, next to the TA, it is pricey though.
Have Fun
