You are welcome - glad to help.
From what I remember the self embark was close to 730 am when it began. We were the second or third luggage tags called and that was between 8:15-8:30. We took a
DCL bus to the airport ( took about 45 minutes) and we were there pretty close to 10 am. I read that you should allow for a minimum of three hours for customs and security in Vancouver so I would say anything after 1 pm should be safe.
