Early planners! I've found my people!

We've been tentatively planning this trip since the day we got back from the last one (Oct 2011) but I've been seriously planning since last summer. The trip went from being a week in a cabin at FW in October to a split stay at AoA and possibly AKL in early February. I'm still sad to be giving up my cabin but once I saw the Cars suite at AoA, it was a no brainer. My 4 year old son is Cars obsessed, he's going to flip when he sees it.
The kids are going to be almost 6 and almost 4 when we go and I'm already planning how we're going to tell them. I just ordered an embroidery machine (I've been wanting one for years) so I'm making them shirts and accessories for the trip. For Christmas we're getting a big box and putting all of the vacation stuff in it and at the bottom there will be a shirt for each of them that says something along the lines of "You're going to Disney World!" My son has been asking to go back for months and I keep telling him maybe someday. He has no idea something is being planned. Can you tell I'm way too excited about this?
