Going to Disneyland or Disney World is far from cheap. But this year, on your birthday, if you register in advance on their site, you can get a free day pass to Disneyland or Disney World. Hey, this is a pretty good present, as a day pass costs $69.
If you are already an annual ticket member, and you go to the park on your birthday, you can get a present of equal value. (a merchandize gift card, a special fast pass, or a pass to be used later in the year.)
This offer is ONLY good on your birthday.
Make sure you read my (soon to be written blog) on how the Bargain Queen saves money on her trip to Disney.
