The reasons why they will not be having beer at the royal wedding are ? It’s simple Prince William just doesn’t want that and that’s final. If i was there I really wouldn’t care. I would be happy drinking wine. They probably have the very best wine floating around the tables constantly. If your that eager to get drunk and cause a ruckus, your probably going to be escorted out immediately and then accidentally bruised a couple of times on your head. I would really limit myself and enjoy the royal wedding as much as possible.
