How many Disney parks are and how many days in Anaheim?

There are two parks. Give it at least 2 days each to have the right experience.

There is a special 3-day ticket, it is convenient to know well, for the new attraction of start wars you have to arrive before 7am to reserve a place if you can not enter this new one, see what is allowed to enter because I was carrying a selfie stick and they returned me,

There are two Disney parks in Anaheim (Disneyland and Disney California Adventure). They are right next to each other, an easy walk from many hotels. It is possible to enjoy both parks in a single day, but for a full experience I would allow 1 day for Californian Adventure and 2 for Disneyland.

There are two parks, if you want to go at 2 a day for each park
