Some brilliant photos here, SMR. Will the renovated entrance area make it possible to queue indoors?This is the principal drawback with the facility at Twycross, IMHO.
The idea, detailed in endless detail in the planning application (it goes on a bit to say the least), is to reduce queuing time and streamline the entrance experience. The queues for the actual turnstiles though, won't be indoors.
That said, once you've got your tickets you could wait for the actual zoo to open in Café Bembe, the shop or even (supposedly) in the elephant house.
