Britney Spears 2011 summer tour confirmed/.?

So on GMA this morning Britney announced a summer tour for 2011 and i would like to go to it but i live in Columbus, Ohio and she is not coming to Columbus she is going to Cleveland, Ohio and Philadelphia, Pennsylvania. and i was wondering which one would be a faster drive to get to, the Cleveland concert it in Quicken Loans Arena and the Philly concert it in Wells Fargo Center arena and i need to know before i buy tickets i need to get them ASAP before they sell out.. (: thank you.
