Hi Patricia,
There are not any permanent meet and greet locations for the characters from Alice in Wonderland in the Magic Kingdom. However, I do have a few suggestions for you:
* Check near the Mad Tea Party in Fantasyland. I have seen Alice, the Mad Hatter, the White Rabbit and Tweedledee and Tweedledum there on occasion.
* You can see Alice and the Mad Hatter in the
Celebrate a Dream Come True Parade in the Magic Kingdom.
* Check the Times Guide when you enter the Magic Kingdom to see if it lists anything scheduled during your visit.
* Check with Guest Relations or a Cast Member (preferably one near a phone at a cash register in a merchandise shop) who can call the "character hotline" to find out what times, where and what characters are appearing in the park.
* Arrive at the Magic Kingdom early. There are usually characters in Town Square during the morning hours greeting guests as they set out on their magical journeys down Main Street and you never know who you will see.
Now, if only I could find Johnny Depp appearing as the Mad Hatter (or Jack Sparrow) in the parks. Wishing you many magical memories :-)
