Loire Valley's biggest price ticket?

We made our annual visit to the International Garden Festival at Chaumont-sur-Loire, it was interesting to see that they no longer offer a 'gardens only' ticket option. 

For people like us who visit every year and don't necessarily want to visit the chateau interior every time it is slight financial loss that might otherwise buy us an ice cream or drink at their refreshment stop but would probably still say that  for the overall experience it is probably still good value for money.

This year's festival,in our humble opinion, wasn't as good as some of the previous years but still gave us some delightful highlights...
