When we went, we stayed in a Disney resort hotel.
That gave you unlimited access to all the parks, and a shuttle service to and from.
So, basically you could go to half a dozen each day if you wanted... with no queuing.
Another great theme park is much nearer to home, Portaventura, near Salou in Spain.
It is, (or was) a Universal Studios park, and it is excellent.
Every year they open new rides and attractions.
Again, if you stay in one of the many resort hotels, you get unlimited access to the parks, and a 'fastpass' to avoid queuing.
I have been many time, I highly recommend it.
