Probably should have mentioned that!
Toilets is a big one, not enough toilets, not big enough, queues blocking the entrance/exit. Upstairs has two exits but downstairs the one I used only had one way in and out.
The general size of the concourse. I hated going down at half time at goodison at times and although there's more space, its like they forgot people would queue for food. Metlife and even other none football stadiums I've been to in the last few years had more space and in some cases those stadiums were smaller.
The use of the plaza (and this might change and probably isnt a priority right now) wasn't great in some ways. Big queues for programs, big queues for drinks and food. Just didn't seem well planned.
