Ack! Totally forgot!
Two great restaurants at the Studios - the Sci-Fi Dine-in and 50's Prime-Time Cafe. They are more than just food, but entire experiences, and kitschy as hell. You'll love 'em! You'll want ADRs for both of those. And, I'd totally recommend the 50"s Prime Time Cafe for your birthday lunch or dinner. Make sure they know it's your birthday. You'll find out why.
To help with your pre-travel excitement, I recommend reading the "Kingdom Keepers" books. They are young-adult novels that take place at WDW after dark when the parks "come alive". They're a fun and easy read and very imaginative. Just don't blame me if you get nightmares of the IASW dolls coming alive and attacking you. You'll have to read 'em to see what I mean.
If you have time to kill and need to rest your feet, see Fantasmic just to laugh at the plywood Mark Twain raft. It's horrendous.
