FYI, they have a stop on one of the two routes for the airporter bus from YVR to downtown - $17CDN roundtrip isn't bad! The routes alternate every fifteen minutes, but even if you just miss the buss that stops here you can take the next one to the Hotel Vancouver and walk (about 5 blocks) instead o f waiting the extra fifteen minutes.

I was in YVR two weeks ago earning my OneWorld segments on CP, and stayed a block away from the Sheraton: the YMCA facilities probably don't compare (including a communal bathroom/shower), but the rate of $40CDN/night can't be beat!
