Hi we just returned arrived 8/7 returned 8/28. We did
free dining and upgraded to the deluxe dining plan. The longest we had to wait was Le Cellier 40 mins (due to eat at 8pm sat down at 8.40) and Plaza at MK was also 40 mins.
We had adr's for the full 21 days we were there and every where else we were either sat after approx 10 mins wait or if we arrived early we were occasionally seated early.
Enjoy your trip
