[QUOTE=johnkimv;935437]I think (I might be wrong) that if you take the ticket to get in on your birthday you can update that one to a AP and just pay the difference. I was under that impression as I plan on doing that in April when my DS turns 3 and is no longer free!! :frown:[/QUOTE]
I got this from the Disney site:
Q: Can I upgrade my free birthday ticket to another ticket type?
A: Yes, the free birthday ticket may be upgraded to another ticket type on your birthday. However the celebrant is responsible for the incremental cost and the new ticket may only be used by the celebrant. The 1-day Magic Your Way ticket good for 12 months (an option for certain passholders and multi-day ticket holders) may not be upgraded.
