Exchanged the voucher at the bus kiosk outside the arrivals hall in the airport and hopped on the Aerobus. The tram and bus tours are all great - We had the ticket for 48 hours, unfortunately the boat tour didn't begin operating until the day after our ticket expired - read all the times & details carefully!! I recommend the Lisbon 4-in-1 and I would buy again if returning to the city as there is so much to see.

The best way to get to know the city, but challenging at times

It is the most cost and time efficient way to see the city. Despite all the challenges with the Knology and buses, the people who work for this company are committed, professional, and extremely helpful. Well worth while. Make sure to print out your ticket - otherwise you may be out of luck

Better than the alternatives

for most part the tour busses were fine. 3 of the stops on the map were closed, which was a shame as i was really looking forward to seeing the bridge. Some of the routes had broken headphone ports, so we couldn't listen to the guided narrative, nor could we change the seat as the bus was packed. On the 2nd half of the blue route the buss driver went off the map, and also took on more customers than there were seats, so you ended up on a packed, hot bus with no option to sit, and of course no narrative. but overall this was a good value, and when you could listen to the narrative, it was informative, and good.
