We have both been to Paris before and this was a great trip made perfect by this tour in the first day. It is a great way of reminding yourself of the city or seeing it for the first time so that you can pick and choose what you go back to see. We were very fortunate with the fantastic sunny day so the top was rolled back and everyone was smiling at the sight of the old CV trundling through the streets. You are at the mercy of the traffic jams but our driver added a little bit of time on the end. I would advise you book outside of rush hour times so that you see more. And fingers crossed for a dry day. We had a brilliant time.
