how far up are the section entrances?

[6xchamps]

first off, thanks for all the info i've already gathered from this section. we are flying in thursday before the buffalo game and thanks to this sight- i've booked a room at the bay motel. to say i'm psyched about it, doesn't do it justice. thanks for the lodging tip.

i was wondering about how far up each section entrance up is. i.e. say we are going into section 109...what row are you in when you go in each section? i ask because i've got two dodgy knees (thank you skiing and the subsequent knee surgeries). going up and down stairs is an issue for me.

any info anyone can offer would be greatly appreciated.

thanks
