I have a question about the 24 hour rebid - if I decide to rebid within by lowering the star rating, can I do it within the 24 hour period after I have logged off, or does it need to be all in the same session? For example, if at 7:00 p.m. I bid on 4 star hotels in certain zones, can I sign off and come back at 10:00 p.m. bidding on 3 star hotels in the same zones? Or do I need to do it before signing off? Thanks!
