This is quite an offer that I saw on TV awhile ago. While at Blizzcon (across the street from Disneyland) I was reminded of it. Basically, if you register now, you can get into Disneyland for free on your birthday. This is mainly for So Cal people, though it is not limited by state. So if you plan to be in Southern California on your birthday, or even think there is a chance just register anyways. I believe registration does end sooner or later, so do it now! Season pass holder? Still register, you can choose from a list of gifts that are really nice.
