Will be at Philadelphia at 6.16-6.17, same situation as you... booked travelodge for backup for 76.50USD willing to stay at Historic District - Penns Landing, Convention Center - Mid Center City, Rittenhouse Square - Business District or University Area, but no luck until now, my max bid for 4*/3.5* is $78, 3* is $70, guess I'll just wail few days to try again...or the worst, see you at travelodge, lol
