But again I would suspect you could only do that if you were intending to use the photographs for commercial purposes? i.e. then you have to get a photographers official ticket.
Regardless of intent who can say what commercial value can be attached to any photo. For example you pay to spectate and believe you can take pics for personal use then you happen to snap Tiger & Sergio going toe to toe in a bunker or Rory having a tooth out on the 14th and put it on your personal twitface page (who might now able to sell the image worldwide) the commercial value lost cant really be undone once its out there
