I put in my wife's email. She accepted the friend request. It's been an hour, and I still can't purchase a ticket for her.
How long does it take for system to update?
Don't purchase a badge for her. Have her purchase it directly on her own account. That way, you guys will get 2 shots at the hotel lottery instead of 1.
Did you try logging out and back in again? Sometimes that helps things update.
What's worked for me: I've added the friend, the friend confirmed it, then had the friend add me, then I confirmed it. Kind of a convoluted process, but it did the trick.
