I just confirmed everything with Olive Garden. We are actually RESERVED this year for the back room instead of a "best effort." Dinner time is 7pm. The back room holds around 40-45 people, and they will also hold a few of the tables just outside of the room for us.
They would really like a final head count on Friday. If you have not yet responded here but will be making dinner, please let me know. Likewise, if you can't make it and already said you're in, let me know. I'll be trying to firm up with people on Friday at Carlisle; I know some won't make it in until Saturday, so. . .
My current count based on this thread is 48 people.
