Thanks for your reply. I figured that was the case... Using the HOTWIRE link, I can get a midsize for $55/day, $220 total for 3 days. I'll keep plugging away with slightly lower bids. Thank you for your help!
I've seen lots of winning bids as low as $12/day for MCO around the same time. I'm up to $45/day for midsize and don't even receive a counteroffer. Is this just a case of bad timing, or am I doing something wrong?
