ThanksYou should be getting the invite email by this week. Ours was also at 10.30 while the website stated that ceremonies are at 9, 11.30 and 2. We were also confused but I guess the 11.30 as per the website is actually the 10.30 ceremony plus 1 hour for Check In and Registration. We reached there at 10 and had to wait outside for 30 mins. You can reach anytime between 10 to 10.30 as doors open at exact 10.30 and there's a line up.
that means even if i go early I would not be able to go inside before 10:30.
