I am only bidding in Downtown Toronto (Priceline), as I need to be able to walk to as many TIFF sites as possible. I did although utilize the rebidding by including other zones that do not have 4* so I could creep up my price in the same day. I have also tried splitting on the 4*, trying 10-17th and 10-18th, both as high as $84 (which is much more than I was initially hoping for). I have not tries splitting my bid on the 3 1/2* yet.
