Thanks. I was trying for a 6:30 adr, but even with the 180+10, we were only able to get the 6:40 time slot. We will try getting there early and see what happens. The worst they could say is no.
We could also tell the wait staff that we want to make Illuminations, and not to "hold" any of our dishes for us. We've have asked that at non-Disney restaurants in the past, and they've been more than happy to oblige, since it opens up a table much earlier for them.
