Without the replies of "they over heard us talking" how did you present your little ones with the surprise that they are going to Disney World?
I am taking my son and we are still a couple of months away. Most likely going to have him find out the day before we leave.
Thoughts I have had, on movie night, put in the Vacation Planning DVD instead of a regular movie and when the video (and his lamenting about how he wishes we could go) I tell him.
Finding someone that can do voices well and call him doing Mickey's voice to "invite" him out tomorrow and then I give him his plane ticket and show him the magic bands
Wrap the stuff that Disney sends and the magic bands as a present for finishing school
He is a 7 year old boy and this trip is the culmination of my saving and working on a trip for well over a year, closer to 2. He has not been before. I think just getting in the car with a pre packed suitcase and surprising him that way would be a bit too much for him to handle.
Whatever you do,
Don't tell him 10 minutes before the limo pulls up in front of the house to take you to the airport when the kids (at the time 13, 9, and 7) thought they were ready to head out the door to school...it'll ruin him for the rest of his life!
Now my kids think that every time I say even the vaguest thing, it's a hidden clue about a surprise trip that we are going on. Poor kids...
Ok...so not so poor and deprived that they were disappointed that they didn't get to help plan and anticipate. They absolutely LOVED the surprise and have asked over and over again if we could do it again.
But, about that surprise trip:
What we did was have everything packed and ready, and made each kid a goody bag for the plane/trip with their magic band, plane ticket, and other essentials. On one side of the bags we wrote:
Who's got it
Better than us?
NOBODY!
On the other side, we wrote:
We are
Going to
DISNEYWORLD!!!!
The flight times/airport arrival coincided almost perfectly with our normal morning routine, so we woke the kids up at their normal time, and they got ready. The only difference was that I gave them specific clothes to wear, but nobody even questioned that. They ate breakfast and the only "off" thing was that I hadn't left for work yet. DS13 asked why I was still home and I said that my manager said it was OK for me to have a different schedule that day

(we never, ever lied to them even once about anything! Misled...ehhh, a little. Lied? Never!) They were about to go out to the car and we called them over to the couch. I started to record and DH told them how they have worked hard, blah, blah, etc, and handed them their bags. They read the first side then turned them over and read the backs. All three looked a little confused and a little happy, and DH told them to look into their bags. The younger ones were thrilled with their gum and new toothbrushes, while (and we can see it all unfold in the video) DS13 read his plane ticket and started to put two and two together. He told the younger ones that our plane was leaving at "10:15am - TODAY!" and that is when bedlam broke loose. They had 10 minutes to get an object of their choice to bring with us and everything else was packed and ready to go.
We had kept the curtains closed that morning, so I watched for the limo to pull up, then told the kids our ride to the airport was out front. They about freaked out when they saw the limo. We got it all on film. It was priceless.
But, like I said....now my kids are ruined. Every time I say anything about going anywhere, they think I have something up my sleeve.
I guess telling them 6 months ahead of time so they can have time to "adjust" and see pictures of the hotel is the best way to go after all...NOT!!!!!! I would do the surprise again in a heartbeat! We all still love watching those videos of the trip and limo reveal!
