I'm sure many of you already know this or have already done this, but on the off chance that you haven't, you can organize a free Enchanted Call from one of the Disney characters (you choose the character) for your wish kid. You can have it personalized to wish the kid congratulations for overcoming a triumph, wish them a happy birthday or an amazing vacation.
I've done it before for Brooke's 3rd birthday and she was just....ENTHRALLED!!!

I had Ariel call--the phone call is short (probably less than a minute total!), but you know the time of the call, so you can plan to put the phone on speakerphone and videotape the call.
Anyways, here's what you do:
1. Head over to Disney Movie Rewards and sign into your account (or create a new, free account if you don't already have one).
2. Enter the code ''ENCHANTEDCALL'' and receive a promotional code for a FREE call.
3. Follow the link to the ordering page and fill out the information (time, date, character, type of greeting). Make sure you enter your birthdate, not your childs (must be over 18 to schedule a call).
4. Sit back and wait for the call to come! You can schedule it far in advance, or have them call immediately.
Enjoy watching the surprise and amazement on their precious little faces!
