I just got cheap tickets for level 4 this year, as I could upgrade my tickets last year for free at the venue on every day except the final.
Enjoyed the final in November, but I'm not going to the final this year. Just have tickets for all day Tuesday and Friday, and the afternoon of Thursday. Guaranteed to see at least one Andy Murray match. I may well try to buy another ticket the week of the finals to see another AM match.
That's also good info for me as I have tickets for wed evening and Fri afternoon so if Andy isn't playing any of them I was hoping to maybe pick some up for the Thursday while I'm down there. Ideally though I'm hoping he's playing one of the sessions I've already paid for
