Our kids were 4 and 7 for their first trip to WDW.
The destination of the trip was a TOTAL surprise to them. We took two half days to drive down to WDW and they did not know we were going to WDW until we pulled off I4 into Disney property and they saw the gates!

Then the hooting and hollering started.
You can ONLY do this once.
The kids can help plan every trip ever after. My kids don't really plan the trip. We do count down the days.

And the countdowns are fun and give us something to look forward too. But the first trip can only be a surprise once. Then they know the destination.
We just surprised the kids a few weeks back. Long story short we took a short trip to the mountains. The kids did not know we were going until the night before. They were already packed though and ready to go. Why? They saw DW pull out the suit case and thought it was to pack for our WDW trip which is getting close. But not that close.

So they packed for WDW.
We told them about the mountian trip the night before because we knew they needed to pack a few more things and we would be short on time the day of the trip.
But they did not know that Grandma and PaPa would be at the hotel in the mountains.

Which was the second surprise.
Now the oldest kid is getting smart. Real smart. On the trip to the mountains she kept asking if there were going to be other surprises. I never said yes or no but asked why she thought there would be surprises.


She would not answer. Eventually she did answer. She said that on our first trip to WDW one of the other surprises was Grandma and Papa being at the resort.
She has me figured out.
We got to the hotel in the mountains and I had to be real careful parking since I could see my parents car so I parked in front of the lobby to unload and not ruin the surprise. The grandparents were waiting in the lobby according to plan. We hopped out of the car and walked into the lobby. I see the grandparents sitting right up front. The kids walked in and were kinda dazed at everything in the hotel....
Eventually, after 30 seconds or so and walking halfway to where the grandparents where sitting the kids FINALLY see the surprise aka the grandparents.
Much hooting and hollering.

Later on they had a third surprise of going off with the grandparents to a water park resort at the end of the weekend.
Surprise Surprise Surprise

Surprise the kids when you can.
An 11 year old could be hard to surprise. But there are LOTS of attractions in Orlando. If the Nephew knows you are Disney Fanatics a surprise is going to be hard. Unless you blindfold him for the trip down. Of course you could surprise him on the day of the trip or the day before. If you can surprise him I would.
Having said that it is not always possible to surprise. We took a nephew to WDW a few trips back and we just could not surprise him for a variety of reasons. He would have known our destination even if our kids would keep quiet.
While we did not surprise the nephew with the trip. We did surprise him along with my mom and the kids with a Illumination Cruise and other events. So if you cannot surprise him about the trip throw in some surprises AT WDW.
We have one surprise for our next WDW trip. Not a big deal but a character breakfast the kids wanted but we could not book in time. But in the end we managed to get a reservation.

But they do not know it.
Later,
