I love your idea of getting EoS for the ride home! Can you use DDP credits there? If you can that would be perfect, because I'm sure we will have some credits left over from the DxDP that we need to use up!
Okay now on to commenting on your posts:
I absolutely LOVE

the Christmas store! John and I bought a few ornaments there when we were on our honeymoon, but they are both too heavy to hang on our little fake Christmas tree!

But I still love them, because one says Our Honeymoon and has the Mickey and Minnie wedding ears on it!
Speaking of those wedding ears, I used to have that antennae topper that you are holding in the picture! I had a lot of fun buying souvenirs on our Disneymoon. I left that thing on my car until it was so weathered that you couldn't even tell what it was anymore!
Come to think of it, you and Weird took a lot of pictures of souvenirs I have bought at Disney in the past! I had that antennae topper, and the last time DH and I went I bought my mom one of those snowglobes with Tinkerbell inside and I got myself one of the pens shaped like Pluto! That is really cool!
I think that trying to create one of those Design-A-Tee shirts would just stress me out. I'm not the best decision maker in the world, and a since the store is so crowded I would probably get nervous having people breathing down my neck and end up making a hasty decision that I would regret later!

I think I better just avoid that place altogether in December!
