Well, after being on hold a second time for 50 minutes (after being on hold initially for 40 and hung up on) I finally got through. I found it odd that I was NOT asked for my AP#, but I WAS asked for both my hotel reservation # (didn't know that was required to make a reservation for this package) and my home address. I was worried it would be all for nothing since it's been reported on this thread that people were told Via Napoli had no availability for their dates, but I got my first choice date, time, and show (12/24 at 4:15 pm for the 6:45 show) with no issues. As others have reported, the connection on WDW's end was very poor, staticky with sound going in and out, and I had to repeat myself multiple times.
Fingers crossed that everyone gets the date, time, and restaurant they're hoping for!
ETA: Guess I'm just a nervous Nellie, but has anyone else made a reservation but not gotten a confirmation email and/or not had it show up in their MDE yet? It's been several minutes since I hung up, and when I make ADRs online the confirmation emails are typically instantaneous, as is the update in MDE. I did get a confirmation number from the CM, but now I'm worried...
