I took the MBNA Thames Clipper from Westminster Pier to Greenwich and it is a fabulous trip. The journey is about 45 minutes and is a great way to see some of the world famous sights from a different perspective.
After reading some reports I was a bit reluctant but as I had nothing but time, I decided to take the trip. Everything was 'spot on'. The trip was great, the crew were helpful - can't say much more.
