Right- the grand opening is on the 6th of December; however, we also know the preview for the general public starts on Nov 19th and the Disney Parks blogs is specifically stating...
"We will begin accepting reservations for Be Our Guest Restaurant in late August for guests hoping to dine at the restaurant after Nov. 19. Keep watching the Disney Parks Blog for Pam Brandons post that will announce when these reservations will open."
So, with this...it sounds like ADRs will start on the 20th of Nov...even though the mass preview officially begins on the 19th. So that makes one wonder- Is BoG going to be walk ups only on the 19th? Is BoG going to be closed to the general public on the 19th? Is the "after" a poor choice of wording and ADRs will open for the 19th as well? Or something else?
My last day (and it's a partial day) is the 21st of November, so the early preview details are very important to my plan.
