We took our boys to Euro Disney for a day. They couldn't go on all the rides but TBH there isn't enough time in one day for all the rides. They have a system where you can get tickets then come back later and avoid the queues and it was worth it to avoid queuing.
They had a great time.
We stayed in a hotel attached to the resort and the boys loved it because it was themed and had lots of amusement in the lobby.
