Hi There -- Been reading your posts re trying to get dining resevations, and back to the MK for the parade and fireworks to no avail.
I realizer the closer you dine to the MK the better, but sometimes we have to take an alternate plan of action, which seems to be your situation at this point.
I didn't notice anyone responding to your post mentioning Boma's buffet at the Animal Kingdom Lodge, or the Cape May Cafe buffet at the Beach Club resort. We have dined at these restaurants, and found them to have good food, with a preference of Boma's. Both have a varied menu which should satisfy any picky eaters in the group. As both resorts are off the monorail line, your chances of getting a reservation might be much better. Just thought I'd present a few more options.
Happy Disney Dining!!!
