I did have them done (back in 1997) at Goofy's Kitchen. There was a disney animator there and he "drew" my kids while we waited. They now hang in my hall
I can't imagine that there wouldn't be somewhere to have it done. I go at the end of this month, I'll try to check for you.
Do they do the silhouettes like at WDW? We have had one done of our son each time we have been to WDW with him, so it would be fun if we could keep up the tradition. Thanks for any info!
