With a 3 year old girl, here are the big things you need to know:
Get there 30 minutes before opening, for rope drop. This gives you the emptiest park possible for the first couple hours. Take an afternoon nap, and return to the park in the early evening for shows and if you can, stay until closing...this will probably be midnight. The reason for this, is the park really clears out after fireworks/fantasmic's first showing.
If you want to ride peter pan, make sure you make that your first ride of the morning, even with Magic Mornings...be sure to use this for your FL rides, you will find short lines and they are mostly child friendly
If your daughter is easily scared, snow white and Pinoccio may be a bit scary for her in FL.
Be sure to go to bugs land in DCA. DO NOT do the show it's tough to be a bug, it is quite scary for little ones.
Go at her pace and watch the magic through her eyes and you will have a wonderful time!
My boys LOVE the chocolate chip cookies from the bakery...they're as big as their heads
Pixie Hollow is where all the fairys are, if she likes those.
Enjoy your trip. If you have any questions about taking little ones to DL feel free to ask me. I've gone several times with ages 2 months-5 years
