I'll be staying in a hotel for 20 days, and I"m wondering what is the best way to get the best deal (Richardson Texas).

I'm not too picky, but I do want to have something that is 'nice...' (i.e, Hyatt Place - large enough room for bed, and sofa). checking expedia, I found the best deal for $100/night, but I"m wondering if there are other methods to get it cheaper. Are sites like expedia really my best bet?

I checked groupon and it doesn't have anything beyond 5 days. I'm a bit worried about priceline just because I don't know what i"m gonna get and I don't know the location (I want to drive back to the hotel to have lunch with my spouse).

Any ideas?
