We used them in 2014. We really enjoyed it and thought it was a good experience for the money. But others in our cruise meet group had a different person as guide and did not care for it as much.
We looked for bears at the river where the salmon were but it was really warm the day we were there, so no bears (I guess they like the cooler morning weather). We were taken to some spots with great views of eagles/nests. The rest of the tour was not animal focused so we weren't really looking for them. We visited the totem pole park and museum (I forget the name) and a few other places around town.
It was a nice tour of the city and surrounding areas.
