Bit of a weird question but does anyone know how long the Britney Spears Circus Concert goes on for? I have tickets to see her at the O2 on Saturday 13th of June and am trying to work out if I can be bothered to go or not.
If I go, I need to book train tickets and I need to choose a return train but I have no idea how long the concert goes on for so I don't know which one to pick! The concert starts (or possibly just means you can enter the Arena) at 6.30pm - is there anyway to find out how long the concert goes on for? Would Ticketmaster or the O2 Arena know?
Also, how difficult is it to get from Liverpool Street to the O2 Arena? I have not been to London in years and am very worried I will get lost!
