I did not receive an invitation, but made a fastpass+ reservation using the helpful link found here on this thread. I am happy to report that I had absolutely NO problem at all today when I checked in at BOG. They had my reservation in their system, with my food selections in the screen at the first check in desk. When we got to the kiosk to pay however, our meal did not show up there. We re-entered our choices, minus the dessert as we decided at the last minute that we did not want the dessert. When the food arrived, lo and behold there was the beautiful chocolate cupcake that was part of the original order. So, something got mixed up somewhere along the way. When we got back to the resort this afternoon in the middle of a BIG rain storm, I asked for a print out of our magic band charges. What we were charged for was the modified order that we made today, not the original order.
Interesting......
