Found this site to be the most informative:

I honestly can't remember what colour their vests are..............but you will be able to find them easily......or ask a gate agent.
Sorry, H & G
You can buy an all day pass at any SkyTrain station...........other than the ones at YVR. Not on the buses though.
If you Google Greyhound Station in Downtown Vancouver it show a map with the closest SkyTrain stations. They are the little blue rectangles.

This is good information for those of you who want to take SkyTrain when you land in Vancouver.
One thing you will see is a new "Add Fare" of $5 for anyone leaving YVR. That makes the fare to downtown $8.75 and the fullday fare pass is $9. Unfortunately the SkyTrain ticket machines at the airport will not sell you a full day pass so you need to go to one of the ticket outlets in YVR to get that.
There are lots of very helpful Airport Volunteers that should be able to direct you to where you can buy a ticket. The link above says the 7/11 in the domestic terminal, but I think there are other places as well.
