Thanks for the help.
Got to the page and filled everything, when I hit submit, I got an error saying my credit card had an issue. So I have an hold on my credit card and the order would not go through, I will wait until that falls off and try again. I have over 2 months. Glad I started looking for it early!
When I called the help number, the young man suggested I could also just call Disney Reservations and have them "add it onto my reservation"? He was a the photopass help number and did not seem overly sure of what the problem was.
