This had to be the worst tour I have ever taken. The tour guide did not slow down for pictures. Several times she could not remember certain things. By the time she announced what we were seeing, we already passed it. She was talking to herself regarding the traffic which I was not interested in.Please get a better tour guide.
I loved this tour. The bus driver was very informative, discussing Portland's history in all the different areas we drove through. We went through parts of Portland that I didn't even know existed! And I live here. I'm having another guest in town today and we're going to go on the Hop On Hop Off bus tomorrow. It's a perfect way for visitors to Portland get a true picture of this beautiful city.
If you have time it's worth doing. But make sure you want to get off before getting off at a stop otherwise you'll be stuck there for an hour before the next trolley comes.
