Pretty sure for DL the operational logistics were announced at the same time as they announced the opening date. The first three weeks were by reservation only, with a 4 hour time slot, and no stand-by. After that the time limit was removed, and there would be no reservations.
Right from the start for DHS, they said there would be no reservation system at this time. But that access would be limited - in other words, be prepared to not get in!
As has been said before, the EEMH are in lieu of the reservation system. And after that a virtual queue is almost certain to be used to control access once the land fills to capacity.
