Do see the shows...

Something I hadn't considered when we made our plans was that there are shows at Disneyland that distract the kids for 30-45 minutes. We saw the Lion King and Tarzan shows on our second day. You don't pay extra, you simply pick up tickets at a particular location for each show. See the park brochures or talk to the staff at your hotel for details.
On the third day, we saw the Animagique show at Disney Studios. A good show for the young ones although it was another example of how Eurodisney is a bit run down. Some of the costumes were showing their age and parts of the set itself looked a bit old.

The Tarzan show is a must see. Very cool "trapeze-like" act. The Lion King show was very good as well.
