Excellent park for younger kids. My 10 year old loved it.
Our experience was few or no lines, mostly friendly staff, little or no smoking, free parking, picnic area, and reasonable pricing. All of the reasons I avoided Disneyland.
The shows were fine - especially the last one with impressive stunts.
Almost entirely French-spoken so you may not understand the shows entirely but we understood enough to enjoy and stayed all day.
Above 12 years old or so will probably find the park very small and childish.
If your kids like animals, be sure to take the train ride which gives a 15 minute break on the far side of the track to pet some goats and ponies.
Pick up a brochure for this site in a local information booth. They usually contain discounts. You can save more online but must reserve 7 days in advance. Pretty risky with French weather.
