Another tip. I sign into my disney account on my phone but also on into my account on my DHs phone (he doesn‘t even have a Disney account since I usually book everything). That way any mobile food orders go to both of our phones in case one person orders but the other picks up the order. Obviously all FPs are on both phones that way too.
I also take a picture of the physical tickets as soon as they give them to us the first day. Then I text that to DH and DDs (who are old enough to have their own phones). This way, if DH and DD are in DCA, for example, and we have 4 FPs for GOTG, and other DD and I are in DL and aren’t interested in GOTG, they can scan in with our two tickets (photos of the tickets or via the FPs in the app). It seems redundant, but one time the app went down parkwide, so we could not access our FPs in the app. We were still able to use our FPs because we had paper tickets and because they had photos of our tickets (they wanted to use our GOTG FPs but we were at HMH, so they didn’t have our paper tickets to scan in as “us”). Hope this makes sense!
