Glen's right -- the KoA has "kabins", and Nancy and I stayed in 'em for years. They're fine - everything but water/toilet -- about $60/night including tax, title, and license and you get a double bed and a pair of bunks. Maybe less at an event other than SpeedWeek. They'll almost certainly sell out of kabins by the 10th of January (for SpeedWeek) -- call there NOW, ask for Lucy (she's the manager) and ask if you can be on the list.
The KoA RV park usually sells out during SW, too, although not quite as quickly as the kabins.
Last year I got rooms at Super 8 around this time of year -- for about the same price as the KoA, and I hear they've got running water in the bathrooms -- better than walking 75 yards to the throne room.
Then there's always the ploy of calling the Red Garter Casino and telling them you want (the specified dates) and "No, I'm not a racer" -- so they give you the cheap price. Tell 'em you're a gambler but not very good at it -- maybe you'll get their real low rates!
Oh, yeah -- I just reread your post and you say you'll be there for WoS. Wouldn't hurt to get your reservations now, but shouldn't be nearly the hassle or the expense of SpeedWeek.
