We had a F! lunch package in January, and our seating time was 3:05 for a 6:30 F! show. A bit late for lunch and a bit early for dinner, and not much different from the dinner F! package times. But we still enjoyed it!
We arrived 45 minutes in advance and the reserved seating sections were mostly empty. We were unable to get the dinner package at our 90-day mark (it was still 90-days then), but the AKL IPO office was able to book the "lunch" a few weeks later. I know the dinner packages were sold out when IPO tried at 90 days, and it didn't affect our ability to get a seat (we had 12 in our group and all sat together down front).
