What a wonderful magical memory that you'll have forever. It just takes a special CM to make you feel like you're the only one there.
We had two amazing moments with my niece, one with Peter Pan and the other Aladdin. While on the Family Magic Tour, Peter took her hand and skipped into Mickey's Philharmagic, sat next to her and then skipped out to the private meeting area.
Her Aladdin experience happened while walking through the market in Morrocco. We were just milling about checking out the back shops and lo and behold, there is Aladdin. He told her he was looking for his magic carpet and could she help him find it. They looked in the shops and whatnot and then he mentioned that he was late to meet someone and asked if she would like to join him. He then took her hand and brought her out to see Jasmine and introduced her as his new friend that was helping him look for the carpet.
She's almost 16 and still remembers both of these special moments and I'm sure your daughter will remember waterplay with Belle.
