NOT WORTH THE $$$$
Waited for over 2 HOURS! Trolly's did not run on time. When they finally showed up...3 of them were FULL! They finally added an overflow trolly. After waiting about an hour in Gastown, trolly's were again a no show. We wasted half our day waiting, then having to walk back to our hotel as we had spent our transportation budget for this hop on hop off trolly. I would advise taking the red bus option, as they seemed plentiful and on time. The trolly co. had alot of excuses, such as, alot of cruise ships in town, unforseen road construction, etc...
The hotel did offer us a refund which we gratefully accepted. The damage, however, was done and our time in Vancouver was over. We did not get to see or do several things.
