If you could take a 6yr old boy to only one park? Which would it be?

Disneyland

I would say Disneyland more specifically Fantasyland were there are lots of wonderful kid friendly rides. There are also shows at the Royal Theatre they may enjoy! There are so many wonderful things to do for days at Disneyland!

If you can take him to Disneyland he will enjoy it more but if you can do both parks

Disney land is more child friendly and has a lot to do for the younger ones. It offers a lot of classic attractions that people of all ages enjoy

Disneyland side.
