I tried to call the number to see if I could sign up in advance but was told that you can only sign up at the restaurant. We went to the one at Downtown Disney (had $50 in gift cards from MyPoints, woohoo!) and the wait was over an hour and a half. I walked up to the counter, paid my $15, filled out the form and got my temp card and cut our wait to about 15-20 minutes. Actually the guy that was at the podium when I asked about the wait laughed when I came back up - no one else had figured out how to "beat the system" - LOL! We eat there every trip, so the $15 wasn't just for the seating that night - it definitely WILL get used and I'll make that money back.
