Vancouver -- Stanley Park question

[bbjaspan]

We will have 2 1/2 days in Vancouver before our cruise departs on June 8. One of the places we definitely want to visit in Vancouver is Stanley Park, touring around the park, stopping in several locations. We just saw online that the Stanley Park shuttle bus service does not begin until June 19. :-( Does that mean that if we do not want to walk the whole way (Whew!), we must rent a car? One of us has not been on a bicycle in MANY years, so that's not an option. There is a horse-drawn carriage ride, but that's only for 2 hours and I assume that's a fixed route with no stops.
