I like the idea of going other places as well. (I did growing up- though it was limited to places we could drive in a day or two). I've come to love Disney for the family time I had there. Plus, my parents encouraged us to talk to the employees at the world showcase to learn from them. Traveling to these countries was not an option for us. Perhaps one child isn't too expensive to fly there but I was part of a family of 5. Airfare for 5 is expensive (thus driving a straight 18+ hours to get to Disney).

We did alternate Disney with other trips- beach, mountains, even a bit into Mexico since I have an Uncle we could stay with in Arizona so we didn't have to worry about hotels and could use the money to fly.
