Katrina,
OK, with a afternoon arrival, and midday departure, I am assuming no parks on either day. And here is what I would do;
- September 15 - Arrival Day
- September 16 - Magic Kingdom
- September 17 - Epcot
- September 18 - Hollywood Studios
- September 19 - Magic Kingdom
- September 20 - Animal Kingdom
- September 21 - Epcot
- September 22 - Magic Kingdom
- September 23 - Departure Day
You might consider keeping the 22nd somewhat open, as after 6 park days you may want to do a second day at Hollywood Studios rather than a third day at the Magic Kingdom. Also, with regard to water parks, I would do them on the morning of the 17th, and the afternoon of the 20th.
So what is next? Need any dining suggestions? Write me back and tell me the where (what park/resort area), what (table/counter, cuisine type preferences, etc.), and when (breakfast/lunch/dinner). I will be glad to give you some suggestions!
Have a magical vacation!
