As a private group on the ship, even if we don't have enough people for the full boat to ourselves, those just on the ship and not tied to the GC Homecoming, will NOT be interacting with the GC folks.
So it you want to go on a cruise with the GC: The Homecoming folks, you'll have to get your tickets through Gatecon, NOT the tour company. It is a one ticket-one price event! :-)
And as one who travels to Vancouver regularly for the past 25+ years, even with the Sky Train, getting yourself to the waterfront, and doing it in a timely manner, isn't always the easiest. Personally I'd vote for the bus to take us back and forth!! :-)
