If I remember correctly we had an 8:15 ADR for Akershus on a 9am park opening. We tried to get to the park so that we could get in before 8am, but they held us with ADRs at the front entrance until 8am. So we didn’t get into the park until a little after 8, and by the time we got to Akershus it was probably 8:15. We were seated fairly quickly, met all of the princesses, my girls did the princess parade (they were obsessed with Ariel and followed her around, it was adorable), and we were finished and in line for FEA 5 minutes before it opened. I took a picture of the 0 minute wait time since I figured I’d never see it again. We went from there over to see Anna and Elsa where it was probably a ten minute wait. I don’t know how much the five minute difference will cause, but 8:15 worked great for us.
