We are spending 5 days in Vancouver in July before picking up our rental car to drive to the ferry at Tsawassen for our trip to Vancouver Island. What I'd like to know is where we should pick up our rental car? I've read that driving in Downtown can be stressful, so would it be a better option to get a taxi out to the airport and pick the car up there (I believe the airport is South of the city as is the ferry terminal?) Or is there somewhere more convenient out of town? We will be returning the car to Vancouver airport on the day we fly home.
