but with all those people it is going to be very cramped in those small streets going from shop to shop.Well Universal are moving pretty heavily away from generic buildings themselves. It sort of made sense with the original park given the Studios theme. But IOA was much less like that and if you look at their recent builds, the new Simpsons stuff is all heavily themed and Diagon Alley isn't just themed on the inside, you've got the London waterfront look on the outside.
