Hi Jasmine!
There's two places where you can do this, both at Epcot:
-
Mission: Space
- Spaceship Earth
When you leave Mission: Space, you will enter the Mission: Space Advanced Labs area. Here, you will find your image from the ride, and can put on a video postcard and send to whomever via email.
My personal favorite: At the end of Spaceship Earth, they will have a "Welcome to Your Future" segment, customized to some initial questions they ask you at the end of the ride. (At some point at the start of the ride, they've already taken your picture). The segment is about 30-45 seconds, with your face placed on animated bodies. When you get off the ride, into the Pavillion area, there are stations where you can locate that video, then send to your email for later viewing or download. Pretty cool huh?
Good Luck with all your planning!
