This was fun, but here's my take: Tour description didn't exactly match. Viator's rep picked us up on time, and was profess'l and friendly. Dropped us off at port, handing us off to the actual boat tour operators. Tour was listed as 9am-1pm (approx 4hrs) but was actually 9am-2:15 door to door in Miraflores, could easily have been longer if boat ran late, people swam more, hotel was farther etc. It's really a tour to go see sea lions w/ oppty to get into water with them - that was fun but unexpected. Yes, lots of birds along the way, The boat tour operators were friendly and knew what they were doing. Would definitely recommend for nature lovers, boat trip fans, and those with true 1/2 day free. Also, 3 people on our boat ride got seasick even with medicine, so word of warning on that would be good. Again, enjoyed this for sure - just wasn't sure what we were exactly in for. Guests could probably save money by showing up to Callao directly at the booth for 10am ride, but transfer service is good for not having to deal with how to get a taxi back from Callao once done.
