I ended changing my plans: staying in Chicago on 6-7 and 11-12. I got the Allerton on Hotwire for USD 89 (USD 110 after tax) for 11-12 and got Hotel Sax for 6-7 through Priceline Express Deal at USD 136 (USD 160 after tax). Not the most ideal, given the price level this year, I guess this is the best I can do without too much bleeding from my wallet. In the past, 3 or 4 years ago, I never had troubles getting a (better) hotel in the same area at most at USD 100. Time has change everything, I guess. Let's pray that the hotels will give some good experience (and values). In any case, thank you for all of your helps.
