For me, it's the amazing attention to detail - the sound of tap dancing and piano lessons from the upstairs windows on Main Street, the sparkling lights in the pavement in Future World, the claw marks on the floor inside the Country Bear Jamboree, Fire Rock Geyser at the Wilderness Lodge. I could go on and on about the tiny little things that mean so much to us!
Also, it's about remembering and reliving every single thing that is wonderful about childhood - family, holidays, Disney movies, a belief in magic, the thrill of discovering something new, having no worries, being somewhere that is totally familiar and comforting, being in a place where you feel loved, etc. - all rolled into one incredible feeling.
Perhaps, the most magical thing for me, is seeing my very serious husband relaxed and acting like a child. And this is from a guy who told me, "I don't really get Disney," before I dragged him along for the first time. Now we're taking our baby for his first trip in May and DH is more excited than I am!
