For anyone contemplating taking the Quick Shuttle between SEA and Vancouver, be aware that a new stop has been added at the Seattle Premium Outlet at Tulalip (about 1/2 - 3/4 hr north of DT Seattle). My experience is that stops take up a lot of time, and the offramps to this location can get really backed up some days. The 4:10 trip time between the terminus in Vancouver and SEA has been optimistic for a number of years. I think it's much overly so now with this stop (albeit, like BLI, is by reservation only).
