Our AK day had early EMH (opened at 8:00am), and we wanted to enjoy all the night time activities through closing. We decided we would go back to our hotel for a break after lunch. That was the main reason why we were OK with doing a lunch at Tiffins (JB dining package), because it did seem like it would have been a "heavy" midday meal. Our party of 8 (2 families of 4) stayed at the AoA suites, and several of us had "doggie bags" for our leftovers, which we took back to our rooms, left in the fridge, and enjoyed later (yay for the microwave ovens!).
As for our experience at Tiffins, everyone loved it! Wonderful decor/atmosphere, exceptional service, and delicious food! Unfortunately, the JB shows were canceled the night we were there. (A CM told us that our tickets would be honored for 5 days, but we only scheduled AK for one day, so we never did get to see it.) I have always known that Tiffins was a signature restaurant, which required 2 TS DDP credits, but we all felt it was well worth it with the show dining package, since it also included an appetizer!
