I would like to book a shuttle from the Grand Princess to San Francisco airport. For those that have been on the Grand, what would be the latest time that we should book the shuttle. We are travelling to Hawaii on April 12, 2018 and returning April 29, 2018. My flight is a 2:30 p.m. I don't know what time passengers must debark from the ship so if someone could advise me that would be great.

Thank you.
