I am looking for advise on where best to go with children (9-14 years)
in Paris, France. Should be fairly central and not for example
Disneyland-Euro outside Paris.
There are no doubt many websites that offer something for children.
What might be interesting is f.ex. testemonies from people who have
come across something not that commonly known but highly appreciated.
But other websites with suggestions for children (incl. package tours
where the parents could relaxe a bit) would do.
As a supplement - but not a must for an answer:  Where could one find
family accommodation centrally - ideally two adults and three children
in one large room ?
Answer may be in English or French or a mix.
Thanks - Alsinger
