We always stay here when we go, about once a year.  It is super cheap (like $30-60 a night), it has a bowling alley, and the place is huge.  There's also a movie theater if you get sick of the Vegas scene.  It is off the strip, but there is a shuttle that takes you to the middle of the strip, so it's pretty convenient.  The food isn't that great at the main restaurants, but there are new places like TGIFriday's and Fudruckers, so things are on the up-and-up in that department.  There are tons of slots since the place is enormous and lots of cheaper slots and tables.  I'm already looking forward to next year!
