boltbus also stops really close to Amtrak. Just walk to the bus tunnel and get off at Westlake Station and your within one block of the Westin. The bus in the tunnel is free in the downtown zone. I'd vote for Amtrak or Boltbus.com

Quickshuttle is fine but as mentioned it stops near the space needle vs downtown and won't drop off at hotels in downtown.

I've never heard of the Bolt Bus. Looks great. Does it stop for pick ups anywhere other than downtown Vancouver?

Update:

Took the Quickshuttle from the Country Store, 176th to Holiday Inn (?) downtown, Seattle. I would NOT do this again unless I was extremely broke. This is not a good way to travel at all. I prefer not to be treated like cattle. Crossing the border was a complete joke - both ways. Prepare for about 5 hours each way.

Thanks for taking the time to update. Shame that you had such a negative experience. While the Amtrak is a bit more expensive, most people have only good things to say about the experience.

if you take the bus again can I suggest Cantrail which operates the coach for Amtrak. it stops at the Hotel in White Rock (Surrey Inn?) then stops at the border and makes NO stops till downtown Seattle. I never liked Quickshuttle as it does make a lot of stops and takes forever.

When I want to take Amtrak I expect to take the train all the way, both ways, without a bus connection posing as Amtrak. I will do so and pay for it, but don't send me on a bus, each way, for part of my trip. Unfortunately that is not what you're getting 50 percent of the time from Vancouver. WTH is an Amtrak Bus? You have to squint, on the reservation system, to realize your Amtrak "train" route is partially bus. I call that Bait and Switch. That's not even half way acceptable. I can only hope this hybrid option is faster than Quick Shuttle - which has to be the worst option - ever. DO NOT Take a BUS (Quick Shuttle or AMTRAK across the border).

Bolt bus is pretty good and really cheap

you asked this question in June and you asked about taking the bus from Aldergrove not downtown Vancouvuer. You got your options. Amtrak runs buses and a train. They don't do any 'hybrid' train bus routes.

The border is a function of the border and crossing it by bus. Amtrak bus and Bolt bus are good options to Quick shuttle but you still have to get off and go trhru customs. I do this multiple times a yr. Sometimes its easy and sometimes you sit there for 2-3 hrs. Only way to avoid that is to take the train from Vancouver.

When slides close the tracks, as is the case today, you're going to ride on a bus no matter what the schedule says. Live with it.
