It was amazing! I just wish there were more details when you purchased the tickets because any price of the ticket would have gotten you anytime on the boat. We did not see the mission because we decided to get on the boat at 7 PM. However, it was great. It wasn't too crowded and it was very small. Highly recommend to get the entire view and feel of Paris.
