Hi Jamie!
WOW - you're planning nice long vacation. Can I confess that I'm just a bit jealous?
Personally, since you'll have nearly a full day on your arrival day, I would recommend checking in at your resort, and then heading over to the Magic Kingdom. And, since you have the dining plan I would suggest making a dinner reservation somewhere in the park- perhaps the
Crystal Palace so you can dine with Pooh & Friends to really get in the vacation mood. Top off your night with a viewing of Wishes! and you'll have the perfect first day!
Now, for the rest of your days, I think you can be somewhat flexible. Personally, I like to alternate longer park touring days with shorter ones so my feet can recover! For instance, if I've spent a full day at Epcot, my next day might be a short one at Hollywood Studios.
Fantasmic! will be shown at 8:30p on Sept 22 and Sept 25. Since you'd like to see this at least one of these days should work. If you're interested, there is also a
Fantasmic Dining Package that might work for you. If you go for this meal plan, our favorite restaurant choice is Mama Melrose's Ristorante Italiano. Or, if you prefer to forgo the Fantasmic dining package, a great restaurant choice at the Studios is the Sci-Fi Dine-in Theater!
And, last but not least, for the big day: your daughter's birthday I'd suggest
Mickey's Not So Scary Halloween Party. There is a party at the Magic Kingdom on the night of Sept 23rd and that seems like a perfect way to celebrate! Be sure to pack a costume (or head over to Pirate's League or Bibbidi Bobbidi Boutique to be made over into a pirate OR princess) and do some Trick-or-Treating!
Have a WONDERFUL trip!
