Easy to follow and find the meeting point. We got there early so had a chance to have some sangria and walk around the market. We stopped at the aquarium which took a little time to find but it was nice and we explored the local area too. The drivers were friendly and super helpful. Great way to explore Lisbon.

This is a great deal Where you get three activities in one deal. Two kinds of yellow bus tours. Both to Old and New Lisbon City plus the Entry to the Oceanarium (Aquarium). You should do this activity in the first 2 days of arrival in Lisbon as it will provide you with an overview of the city. The audio guide commentary is very useful. Simply go to the Yellow Bus Tour Start point mentioned clearly in the instructions or get on the bus at any stop on the route. One complete bus loop will take around 60 minutes and I recommend at least 2-3 hours for the Oceanarium to soak up the experience and enjoy the trip without rushing it. Overall a great activity recommended for solo travelers, couples, friends, and families with kids of all ages.

The Oceanario is gorgeous and worth exploring inside and out. It's in a modern part of Lisbon that's very easy to overlook. The tram ride to the Vasco de Gamas bridge is fun. Unfortunately, the yellow buses don't seem to run as often as the red buses. :-/
