Definitely go to the library and check out a book on going to Disneyland. They make several different ones and they will tell you so much about when and where to eat, best times to go to the park and which ones, which rides to ride and when, etc. They even have tips in them such as the best time to go see the animals is actually before the park officially opens when they are feeding them, because they are all out where you can see them.
I don’t know if you’re library will have these books, though being in Canada. Even if you have to buy one off of Amazon.com, it is well worth the money. This helped us more than anything anyone could tell us.
