I'm presuming by that comment that they're in Royal box on Centre? Not really their decision- the organisers and security will have it planned out for them being on Centre. You really have to blame the schedulers for that, because they'll have know they were meant to be coming today and should have put Andy on CC.
No, was referencing someone elses comment on how nice it was for the Royals to go and watch him. I just believe that day he was playing on the day they visited where as today, I believe they have gone to watch Andy play
