We never got an email. Just the FP on
MDE. This was for Sat 5/13, 9 to 11. we had no problem. They swiped our mb at entrance of park and them they had people with the handheld readers as you enter Pandora to scan the MB again to show the FP. Since you named the people each person you named has it attched to their ticket/acct. The email was not necessary at all.
We had a great time, can't wait to go back at night.
