1) If it's raining, you'll get soaked assuming it's Row C in a lower tier.
2) Dick's Bar and the concourses are the only places at the stadium itself, The Swan pub is a short walk away.
3) Not sure, but probably not.
Ok thanks I booked row c already..thanks for the information...Hello.
Sit near the back, better view.
There's a bar at the ground, otherwise drink in town before heading to the game.
Almost certainly not.
Given that English isn't your first language and you're new to the city I suggest having several reads (and then ignoring the majority of) the clubs travel advice, wherever that is kept.
Enjoy
Can I take a big camera in? I don't have different lenses but a bigger zoom
Probably not, if you did it discretely and didn't use it all game long you might get away with it though. Phones etc normally fine.
