LOL. I'm sure we could swap tickets during the season for a few games. SW corner is one of the better parts of the ground IMO. My favourite parts of the ground are East Upper, NW corner & SW corner
I would put a vote in for the SW corner. I've taken my Dad (69) and son (3) and it went really well. My Dad has no mobility problems which your Dad might, but it's actually a good view and the bar really isn't busy. I like it there
