I have an ADR for the Crystal Palace at 8:35am. I tried for earlier and will keep trying, but if I can't land an 8:05 ADR there, I'm curious as to how entry is handled. I know that they have a special turnstile at the entrance of MK for breakfast ADR people, but do they check the reservation times and hold people back until their reservation time is close? For example, if I arrive at 8am, will they let me in or make me wait until 8:20 or so?
