The hotel website says there is complimentary wifi in all public areas of the hotel and if you are an SPG member you might get free wifi in your room (I believe that depends on your level though). So unless you want to be out and about in Vancouver a lot and think you might need wifi there, it's probably not worth getting. However, remember that there will be a lot of people, if all of them use the free wifi at the same time, it can get real slow. I know I use wifi a lot, but every time I travel to the US for a convention I usually see what I want to do in advance (like sightseeing) and get all the info so I can take that with me and I usually don't get a phone plan for abroad. My opinion only, it really depends on your needs.
