This is one of the best things to do by night in Prague as the views of the city lights and landmarks are stunning. Choose your cruise company very carefully though! We found out after the event that a cruise purchased from the hotel was not the same as that advertised on the company website. We also had to pay cash upfront so we had no protection when things went wrong at the last minute. Advice given at the hotel reception was misleading. The leaflet given to us was not for the trip we were booked on. Prague Expert are a bit more expensive but much better value for money. Don’t touch Best Tour with a barge pole. They did not deliver what was promised and their response to our complaint was unsatisfactory.
