We got really lucky... and snagged a reservation for our December trip. Since my sister and I are over planners, we had our days planned out and park reservations made well before the 60 day window for ADRs, and only one of us handled making the reservations. Since our trip is well over a week, and one of our EPCOT days was towards the end of our trip, we were able to snag a reservation on the day we wanted, and at the time we wanted. Go figure...
As mentioned many times already, the cost is... daunting. So more than likely this will be a one and done, unless we really enjoy it and the Dining Plans come back. Then I might consider it again... but it certainly is something that is more about the experience than the food, so any return trip will be for the novelty.
And to be honest, even if the dining plans come back, there is a better than 50/50 chance we won't use it anymore, as the costs are just getting ridiculous. As I am hoping we only camp at Disney in the future I can see us spending much less on eating in the parks and more on bringing our own.
