Thanks to everyone in this thread for all of the tips and tricks!! We had were in line to park at 9, they started letting cars in at about 9:15. We were in the park by 9:30 and headed to Toy Story Land. After a pit stop, we got in line for Slinky Dog at about 9:45, the long was pretty decent so we thought we had time. We had
MDE on 3 different phones - iPhone 5s, iPhone 6, and iPhone 11 (mine). Well, we were boarded onto Slinky Dog at 9:58! My DH and I kept our phones out, and while riding, I was able to get BG 27 ☺ I only included myself in the group, and went to GET where they added the rest of my party.
Again, thanks to everyone here!!!
