Can I upgrade a 'package' I've gotten from disney.com? I would really like to upgrade to AKL from ASMo, but I don't know how to get there without spending all kinds of money. I've read a lot around here about codes and such, and am wondering can I still use these codes after all has been booked and paid for? Guess I am looking for a little hand holding here. Mom & Dad used to do this stuff for me. <grin> This is the first Disney vacation I've planned, and I want my queen to have the best time possible. It's her first trip to WDW. Thanks!
