They have, but the one thing that hasn't changed is the number of dining places, and now one third of those are back to TD which limits the numbers because they can only manage 2 seatings a night.
This is probably the same number that a bookable dining room can operate because of the numbers of empty tables that are waiting for their customers.
That will eave the walk up dining room very over stretched to accomodate everyone else who want to eat in the MDR.
anyway come September we will find out.
