glen to vegas. . .

[glen]

I am planning a last minute trip to vegas. I was going to go for about 5 days leaving Friday, but one of my friends who was meeting me for a weekend accidentally bought his plane ticket for next weekend (d'oh), so now I might be staying for 10 days. I hear this is a busy weekend (some convention on the strip?, but I know summers are usually slower. . . Can I just get off a plane and get a room someone for about the same price as booking one. I've been to vegas twice and both times I pre-planned everything, but since I'm going on short notice, I'm thinking about priceline and walking to a front desk. I would like to stay on the strip at maybe the imperial palace (cheap. . ) but I don't mind being as far away as the Stardust, Circus Circus. Can anyone give me any quick info on the hotel situation this weekend?. . .
