Up coming stops are announced and you can track your journey using the map over the doors. Not much seating, so you may have to stand, but the stops are quite soft so you won't be thrown about.
The only issue I had was figuring out what direction I was facing (did I want a West or East-bound train?), but otherwise they were foolproof.
One goes from right outside the airport to downtown, probably in about 20 minutes.
It took me about 10 min to get from Burnaby to W Georgia, I took it everyday and, since they come so often, didn't even plan times.
