What Stainlees said. I'll add a caveat, though - - the Red Garter casino bought the old Americin Inn on the far west end of West Wendover a year and a half ago, and I haven't heard any feedback on the quality of the rooms there. Other than that one -- everything from Motel Sux (I meant Six) through the Quality Inn, and even the casinos -- is fine, mostly. In general, you get what you pay for (at least in the way of amenities such as coffee, breakfast, pool, wi-fi, and so on. Any beg bugs are supplied at no extra cost.
The Best Western was also under new management, I heard, and with that I also heard some less-than-positive information. At least through last race season the casinos did NOT have wi-fi in the rooms, evidently 'cause they don't want holed up but rather downstairs, gambling.
Should you prefer camping -- the KoA, down at the west end of West Wendover (kinda behind the Red Garter) offers quite a few campsites for your RV or tent, and about a half-dozen "kamping kabins". We've stayed in the kabins a bunch of times - they're decent and a heck of a lot cheaper than rooms. If you go that route - take along an extension cord/multiple tap strip for your clock, refrigerator, etc.
