We're going to Disney

We are going to Disneyworld for Mason's fourth birthday. We have told him that we will be flying to Disneyworld where he will get to see Mickey Mouse. We are not real sure he gets it because whenever we say "Mason, we are going to Disneyworld for your birthday", we get the following responses:

"We are going to get on the plane. Don't pee in your pants."
"We are going to fly over the clouds."
"We have to go see the ants. We have to go see the web and the spider!"
"We have to scream on the rollercoaster."
"We have to cut the cake."

I guess the comments are somewhat accurate. Though, I am pretty sure he has an inaccurate account of the Disney character lineup.
