We just did a surprise trip for my sons, ages 9 & 5, back in January.
It was a BLAST.
They did not know about it at all.
They thought they were going to school that day (we took 'em out of school two days before winter vacation started).
We packed the car when they were sleeping.
I pretended I got a phone call the night before of friends of ours who live in BAltimore having a party for their newborn baby.
So I told my sons looks like we're going to baltimore tomorrow.
(while in fact, we were driving to the auto train which is right near baltimore)
I wrapped up two Pal Mickeys in baby wrapping paper & wrote, "congratulations" on it, so my boys thought it was in fact a party for the baby.
As we are in line to check in for the auto train, my 9 year old said, "hey isn't this the train that took us to disney."
And I said, "looks like we are driving right by it."
He said, "as long as we are here, can we stop so I can go to the bathroom?"
We said, "sure"
The amtrak people tell us to take things out of our car & my 9 year old says, "why are you taking things out of the car?"
I said, "security."
He says, "are you sure they won't take our car accidentally?"
I said, "just go to the bathroom."
OF course they take our car & when he comes out of the bathroom, he freaks, "I told you they'd take it, what are we going to do?"
My husband, in the meantime is in line to check in at the train & I said, "don't worry, daddy is doing the paper work to get our car out."
I said, "as long as we're here, let's hang out & take some pictures."
My kids were looking at all the people by the station & saying, "they are so lucky, they are going to disney!"
i said, "as long as we are here, let's see if they let us on the train to look around."
Of course we get on the train since we have tickets.
My 9 year old starts to freak out a bit, "we're not supposed to be here, what if the train starts to move, we'll get in so much trouble!"
Finally, we take mercy on them, since he's getting so nervous- we pull out the video camera & say, "guess what- we are going to disney for 10 days."
Their reaction, "WE DONT BELIEVE YOU!"
It took a few minutes of convincing and pulling out the train ticket & disney tickets to convince them.
It was a blast!!!!
I definitely recommend the 'surprise route'
(another year, I made a puzzle on poster board, I drew many disney characters on it & in the center in block letters wrote "we are going to disneyworld". I cut the puzzle in several pieces & gave the kids a piece or two each day of Hanukkah, I started with the harder pieces, but until they put the whole thing together on the last day, they didn't know what it would be)
