We really enjoyed our first look at the city this way.
Our bus driver was awesome. I don't remember his name maybe Eric? He was from California and has lived in the Portland area now for several years. He infused humor into his narrative of the city. Portland is beautiful and we were impressed with all the family parks and things to do. Would definitely recommend this tour.
We were there the day of the eclipse. They didn't communicate that the trolley would be starting 2 hours late. I don't know if they compensated by running two hours later in the day, nobody ever made any type of announcement or notification. In my opinion its not really worth the money. You can just walk most places. There is also just the one trolley running each day.
