So I googled "leave a legacy EPCOT" and found this on
www.passporter.com
"Description: Leave a Legacy is a photo time capsule upon which guests can leave their images on metallic tiles for a fee. The tiles are then mounted on Leave a Legacy sculptures, which are granite monoliths arrayed under Spaceship Earth just inside the gates.
Location: Epcot. The Leave a Legacy Sculpture Garden is just inside the gates, the information kiosk is behind it under Spaceship Earth, and the registration and photographing booths are to the right of the sculptures.
Wait: There is no wait to wander among the Leave a Legacy Sculptures, which are accessible to all and you can't help but walk through them on your way into Epcot. The wait to purchase a tile depends on when you arrive. An overhang shelters guests from the sun and rain while standing in line for tiles. We recommend stopping at Leave a Legacy when you first arrive or later in the day ( but not at closing).
Cost: Tiles are $33 for one face on the tile and $38 for two faces on the tile. 10% discounts are available for Magic Kingdom Club card holders or Annual Passholders.
Notes:
- Tiles may contain only one or two faces. If you are a family or three or larger, you will need to purchase more than one tile to include your whole family on a Leave a Legacy Sculpture (and there's no guarantee your images will be close together).
- Upon purchase of a tile, you are given a locator card (one for one image, two for two images). Don't lose this card, as it is your "ticket" to get a photo taken in the booths, your card to find your tile once it is installed on a sculpture, and your password to access your image on the Web. Note that if you get two cards, the second card is only a souvenirit won't work for photographing your faces, loocating your tile, nor for looking up your image later on the Web site.
- About four hours after your photograph is taken, the tiles are put on temporary display on the side of the Leave a Legacy kiosk under Spaceship Earth. Look for a time and date stamp at least four hours after the time you had your photograph taken (and it may be longer).
- Tiles are scheduled to be installed on the sculptures four days later. So if you get your tile made early in your trip, you may be able to see it on a sculpture before you leave."
