By "main park" do you mean the Magic Kingdom? Or Disney parks only as opposed to any other Central FL parks (like Universal or Sea World)?
The Wonderland Tea Party sounds like fun!
My dd5 and I did the Perfectly Princess Tea at the Grand Floridian for her birthday, but it is a bit pricey. We thought it was certainly worth it considering what a magical experience it was. And my dd has been playing with her Sleeping Beauty doll she got at the tea ever since we got home from our trip in January.
I am considering a Pirate Adventure cruise for her on our next trip (2 hours) so I can do a little shopping w/out her! I love her to pieces, but...she is not yet the shopper I am!
At the Magic Kingdom, my dd loved Dumbo, Peter Pan, Winnie the Pooh, the Pooh playground, meeting Ariel, all of Toontown, Splash Mountain (she is adventurous!), and the Tomorrowland Speedway as well as the Tomorrowland transit authority. I think her favorite part of the whole trip though, was meeting the characters.
One night we were in Toontown around closing time, and all of the characters came out to the store area and had a dance party. All the characters were everywhere, and there were no lines, just lots of great character interaction and fun! I highly recommend this!
My dd also really enjoyed meeting Chip, Dale, Mickey and Pluto at the Garden Grill for lunch. She had a birthday cake to celebrate her b-day, and Chip and Dale wiped some of the frosting from the cake on her nose and then laughed into their hands about it. My dd thought it was great!
