We do get E!, however our red carpet event airs on the 20th. How odd....Not sure if this has been posted so apologies if it has but here in the UK Sky TV has the following description for one of the shows on TV airing on Sunday 22nd at 5pm:
LIVE FROM THE RED CARPET
Harry Potter/Diagon Alley: Join E! as we welcome the stars on the red carpet for the opening of Universal Orlando Resort's Wizarding World or Harry Potter - Diagon Alley.
It's on E! which I assume you guys in the States get also!
