I have a toddler in my family and she's going to WDW soon enough this year....
Side note... And about the whole song and dance of how she won't remember it, there's cameras and video cameras in today's age of technology plus there are memories we adults will be creating for ourselves when we take her. Moving on.
I just keep pointing at Cinderella's Castle and using WDW images on the net and on dvd's to help describe WDW to her. She's just learning how to speak so I just point at something that is WDW like Cinderella's Castle and say "That's Disney world" and she repeats it with a smile!
But I wonder how would you all describe Walt Disney World to your own kids, to your nieces, nephews, grandchildren, etc.
If you like, list their ages, names are optional and how you describe Walt Disney World to them before their first visit.
