2 days was good as we could do longer stops on day 2 and do some parts of paris on day 1 which we would not have visited otherwise.

This one of the best and easiest ways to get around in Paris - surely a huge city. The bus-network is well planned and takes you to most of the "must-see" places in the fastest way. You may use the Metro etc. to get around but believe me - it will eat a lot of your valuable traveling-time - so I definitely recommend this Hop-On Hop-Off service. The buses run very often (sometimes even overlapping) so if one bus is full - just jump on the next. Booking thru isango was a pleasure and saves you a few € too. Recommended!

Had had an early flight from Heathrow, so this trip was what we needed. We saw all the sites around Barcelona so when we were up to it, we could go and see them later. It wasn't cheap, but it was what was promised and learnt a lot from the tour.

Grt and value for all family!

being over 2 days it relieved pressure by allowing us more time to visit places of interest and go and all five of the bus tours
