You're probably looking forward to a day of doing absolutely nothing, except for being served a relaxing brunch. We're sorry for throwing water on your plans, but you can't just do 'nothing' on a Sunday cramped with theatre, sailing, athletics, shopping and a circus.
If you see a lot of teenagers and objects a few tens of metres in the air above the stadium, it's not Quidditch - just a bunch of talented athletes doing their thing.
Sunday morning probably begins at noon for you, after a hard week's work or a late night party. And most probably, it starts off ravenous. Grab a wallet or a sponsor, and head to ITC.
