Here's what I know.
My DW and I are celebrating our 10th anniversary this year, in October. However, we will be at WDW next week.
We have a priority seating at the Garden Grille for Sunday the 13th. When I booked the PS, I told the CM that I wanted to surprise my wife with a re-hitching ceremony.
The CM new all about it and wrote my request on the PS. She also told me to tell the CM at the reservation desk about the re-hitching ceremony (as a reminder!!).
Basically, the servers, Chip & Dale, and Mickey come over and ask us to stand and say our vows, "I do to this... and I do to that..." Then they'll ask me to kiss the bride for good luck we must hold the kiss for 100 seconds!!! As they all count, 1, 2, 3, 4,... you'd think they would count all the way to 100, by 1's, but they don't.
They change the count at 10, and count by 10's. 10, 20, 30, ...
Sounds fun. Again, I am surprising my wife with this next week. I'll let you know how it goes.
