We gave a January Disney trip to our kids one year for Christmas, it was when they were doing the Pirate and Princess parties. We did a scavenger hunt and had our DDs dress up like princess pirates and DS dress up like a pirate to do the hunt. They still didn't get it since a lot of treasures were pirate and princess related. The last "treasure" was puzzle pieces divided up for each kid. It was a craft/make your own puzzle. I wrote in sharpies "We're going to see Mickey in Disneyworld" (or something like that). The kids had to work together to put the puzzle together. They couln't say anything until it was all put together, as they are different ages and obviously the older one caught on first. It was SO fun to see their reactions when it was complete!
The next day we did a Disney everything breakfast (partyware, cereal, balloons, etc.) and watched the planning videos. It was one of the best Christmases we ever had!
