We had a hop on hop off bus ticket that gave us admissions I’m not sure to be honest as an American friend of ours booked everything for us .

Yes

With our tickets we could walk around the ship freely and not have to wait for a grouped tour. Just walk around at your own leisure

Yes. I was not particularly keen o go to this attraction but my husband is a plane enthusiast. There was plenty to keep my interest. Your children would enjoy the submarine & seeing Concorde. Think there were interactive activities for children but didn't really register these as we were on our own. Perhaps take food with you as food in the cafe was dire! There is a food market which includes a good Italian restaurant about 4 minutes walk away, over the main highway. Have fun.

Désolée, je ne sais pas, n hésitez pas à aller sur LE site du musée. BON voyage !

We faced queues only at some particular attraction, such as entry to the submarine Growler due to limited space on it - therefore entry control is a must, and you will not skip it. Another was at GFORCE flight simulator. but because they are only two and a lot of visitors wants to try it. One more was at Space Shuttle Pavilion on VR trip, but because it took too long to wait, we decided not to try. It was on July 4.
