Although I don't have a picture to post, we have themed our family together on our two trips in a non-Disney fashion.
1st trip- DW as referee, DD 5 months as hockey puck, myself as hockey player
2nd trip- we were the American Flag (home made) DW and myself blue shirts with white stars, red and white striped shorts; DD red and white striped shirt and shorts with one sleeve blue with a star, DS all red and white stripes. We were popular when seen together. I'll add a picture later if I can find it.
