I have stayed there, but it was about 10 yrs ago. From what I remember, the village itself is small and tranquil, with a small number of very traditional restaurants and shops. I was a hormonal teenager at the time and I recall it being "boring" but then I was more interested in a girl I'd met at the site and spending more time with her ;-)
In the larger towns of compiegne and soissons, there is a more "big town" feel, and they are not touristy at all (or were not then)
I recall the site is not too far from Paris. We often went and parked near where they were building the stade de france and then rode the train into town. The area was rough, but I guess is better for the building work
The campsite was large and well fitted out. There was a pool and a games room and a nice shop that got fresh french bread each morning.
There was also a play area and plenty of youngsters for my brother to play with and teenagers for me to "get to know".
