Hi, Tiffany!
How wonderful that you get to experience
Walt Disney World with your Godson. What wonderful memories you get to create with him!
As far as things go at Disney, no identification is needed for your godson, and since he is
under age 3, he will not even need a park ticket. However, you may want to have some basic information, such as a copy of his medical insurance, a list of any allergies, and emergency phone numbers just in case. You never know what unforeseen event might happen, and not just for a Disney trip, but any trip, this information will be helpful.
I am guessing you are driving since you are in Florida, but if flying, you will want to contact your airline for any TSA required documents needed for the airport.
Wishing you a visit to Walt Disney World that is full of magic!
Cathy
