Tried every combination of bids+zones imaginable before I finally locked down a hotel in Chicago (it's Monday and I leave on Thursday!?) Started bidding as low as $80 and went up to $110 for 4* in NMA/River North area for the past couple weeks. Finally worked my way up by adding zones and bidding $115 on Franklin Park Area, Hyde Park , Midway Airport Area (MDW), Skokie - Niles - Evanston and North Michigan Ave - River North Area then VOILA!! Mixed reviews and seems like it's hit and miss on whether you get a desireable room or one you'd want to change...hopefully it works out and I'm very pleased with it's location!
