We just got back on Monday - our bands worked for charging all day checkout day as they always do. This trip we left the bags with Bell Services, told the front desk we were done with the room and hit the parks until it was time for DME pickup early evening no issues using bands or charging.
Prior Trip October 15 - checked out of BWI, put bags in bell service, hit food & wine festival until fairly late and then took a cab to our offsite hotel, again no issues.
