I found that the hotel is great for layovers between flights! There's a great shuttle service to and from the airport that comes to YVR for pickups at quarter past the hour and quarter to. The driver was very informative and provided all sorts of information on amenities, places to eat, etc. The shuttle is a first come, first serve basis, so you should reserve your space beforehand when going to the airport.
My room in the Columbia Tower on the 9th floor was very clean and had two queen beds. I love that there's a Starbucks downstairs too. The Chop Steakhouse and Shark Club restaurants are right there as well. There's also a Denny's around the corner.
The pool is nice and big too.
It would be nice to have more lighting in the bathroom so that I can get ready easier.More
