Next time you're at Disneyland, be sure to visit Innoventions in Tomorrowland.
There are great activities there for children - educational activities. Most of the attraction is sponsored by business, but the idea is that it's all innovative things - and who pays for innovations, usually? Business. So, it all fits.
There are several rooms with computers and games set up. One of them is a roller-coaster designing game which is really great. It tells the kids how fast their coaster is going, and if they have hills that aren't supported by the speed of the ride, the coaster can't climb them.
We could spend hours at this attraction. I highly recommend it! And they have activities for kids of all ages.
