We're staying at Chateau des Marais near Chambord for the Jubilee week and hoping for good weather as it's got a nice pool area. Though I think I will get together a list of other things to do in case the weather's not so good. DD is 10 & DS is 7. We're taking the bikes but aren't up to cycling for miles and miles as we're all a bit unfit. 
Any recommendations of what your DC have loved in that area? Thanks.
