Your ticket covers entrance, rides, shows, and entertainment. The only two things not covered is your food and souvenirs.
If you have only one day I suggest on doing one park and plan it and you will have a much more enjoyable time. Plan shows that you would like to see around rides, and meals, use fastpasses when ever you can.
Park hoppers for both sides cause yes therse 2 now the original side and the adventure park. Both are very fun.
Also in California Adventure they serve alcoholic beverages, while in Disneyland they do not.
There all fun. Coasters, a fun day..
