During my vacation to Vancouver from UK in June I plan to drive a hire car to Seattle for the day. Can anyone give me some advice on how long it it likely to take, the best route and what should I expect at the US-Canada border? I have an itinery of things to do in Seattle so I'd like to know how early I need to leave Vancouver so I dont miss any of the reservations I have made. Thank you. This site is fantastic as I have received some great advice on previous postings!
