Wohoo, have a fantastic time! Make sure you get a Birthday button from every park, remember if you haven't already got your entrance tickets, you can get in for free on your Birthday. If you have already got your tickets you can get a gift certificate for the value of a one day ticket to be spend on any merchandise within the parks.
When wearing your button, try and keep count on how many people say Happy Birthday to you, you would be suprised just how many people actually say it to you throughout the day.
Quite often in some of the restaurants, your server will bring you an extra little something if they see it's your Birthday.
Have an awesome time! :sohappy:
