I'd reccomend that you "name your own price" on priceline. Put in a 3 star hotel in the downtown area and bid $50 or $60. The worst that happens is you don't get anything. The best is you get the Embassy Suites for $50.00.
I'd be surprised if you didn't get it. I always do the name your own price when I have the option of really narrowing down the areas. In Desmoines the downtown area is SO small and there are only 3 or 4 3 star hotels. Anything that you'd get would be great.
