You can do it at lunch or dinner AND at the Ice Cream Social. Ask the CM to make a note of it on your PS and when you arrive at the Garden Grille, remind the CM on duty that you would like to do the rehitching ceremony. You will love it!
We did it in May and got a certificate and a cake. We thought the cake was enough for 6. The ceremony is not that long, but the best part is kissing until the count of 100. They count to 10 by 1's, then to 100 by 10's.
Bring a camera to get some pics of the event.
