Well first of all, welcome. This is my sixth time going, so I know a few things
The first thing I did when I found out I was going to disney was made a list of all must-see things at each park and wrote down a few tips. So-
Magic Kingdom-
*Get there 30 minutes before opening.-If you do this than you can see the main characters (mickey, minnie, goofy, donald, pluto, etc...) ride in on the train and then you can get autographs, pictures, etc...
*Dining-
Cinderellas royal table-make reservations 180 days in advance-character breakfast
Chef Mickey's-same thing
*Rides-
Jungle Cruise
Pirates of the Caribbean
Splash mountian-one of my favorites

Big thunder mountain railroad
Haunted mansion
It's a small world
Mickeys Philarmagic-amazing show
Ariels Grotto-your dd will love this, she'll get to meet ariel and get a pic. with her. There are fountains that spurt and kids love to play in them.
Toontown-fun for all the kids-Mickey's country house, toontown hall of fame, minnies country house, goofys barnstormer-good starter rollercoaster, judges tent, donald's boat-great activity-it is an interactive boat that is a water-play area-me and my brother had a great time even though he's 10 and I'm 15
