The picture thing is common in the Wisconsin Dells as well. They take your picture before you board the boat tours and have a package ready for you when you get off the boat. Typically its a 8x10" and a couple smaller pics for like $12.
haha they do it when you get on the maid of the mist in niagara falls, go up the cn tower, do the 1000 island boat cruise. geesh i didnt realize that there were any tours that dont do this.... :-|
