Marie is a great character greet! She was so sweet and DS was sooooo excited. Every time we walked through Main St his head would just dart searching for her.
Ariel was amazing. She was his first character greet, we had just arrived: walked in and saw the parade, then when on his first Disney ride and he was feeling sooo overwhelmed. She was so great with getting him out of his shell (ha!) and got a few smirks out him. He was still a little shy so she said she had a present for him and gave him a big kiss! Well, he walked out of there skipping and singing and didn't stop for our entire trip! Totally set the tone!
Winnie the Pooh at Crystal Palace was his absolute favorite I think. He was the only character that he got down and ran to- right into his arms! Every other character I kind of had to introduce him to and help him to warm up, but not Winnie the Pooh!
Can't miss though has to be talking Mickey. DS had told me that Lightning and Mater at HS weren't the *real* Lightning and Mater because they didn't talk. When we walked in to see Mickey having a conversation with his photographer he just about fell out of my arms! It was his 3rd birthday, and he was wearing his birthday pin, and Mickey led everyone in singing him Happy Birthday! And as another poster said, Mickey was conversing in different languages with different guests- just unbelievable. We got my favorite picture of our entire trip with Mickey. I wasn't about to wait an hour for him (we had fastpasses) but knowing what I know now, he'd be worth the wait!
