I've given some casual thought to this in the past, and I have a short list of where I'd like my neice and step son to scatter my ashes, and 7 Seas Lagoon is one of them (of course, so is somewhere around Martinsville Raceway...). Disney could make a fortune if they did something along the lines of a columbarium, but since they wouldn't let me mom do a Leave A Memory tile in honor of my Dad, I feel it safe to say they will never invite mortal remains or their remnants to knowlingly end up on Disney property.
