Our tour contact was 1/2 hour late to register us and we had to literally run to the train after clearing security, 4 people in our tour did not make the train. Our guide Michael was knowledgeable, friendly and did a great job of dealing with a very difficult situation. Great trip otherwise.
Lunch is iffy, but otherwise highly recommended. I looked up the train prices, and it was a better deal to book with the tour. Despite the delay with the train itself, Michael knew how to make sure we can still make the most of the remaining time. With the lunch option, I felt like I should have picked the river cruise instead, but it wasn't bad. There wasn't enough time at the Louvre, but at least I got the highlights.
