No it's not April Fools Day and it's absolutely true. Disney has announced that anyone and everyone can get into either Disneyland or Walt Disney World for free!!!! What's the catch? You have to go on your birthday. But wait, there's more!
If you allready have admission, such as a seasonal or annual pass, you can choose another option. The most exciting alternative is you can get merchandise equal to the cost of a 1 day ticket! Currently, that's $75 at WDW!
