I just purchased the one day MM last month during Marathon Weekend. I made the purchase on MDX the day before. They didn’t tap my band for any pics before/during/after the race since they just use your bib number, so as soon as I got to the parks later that day, I took a character photo so I could get PP to tap my band and that activated it. Worked great. The race pictures take a few days to load but all the early morning ones showed up too
I had to call about one missing photo, my bib number was slightly obscured but they found it even 3 wks later since I knew the exact time I was in front of the castle. Don’t worry and good luck!
