Clarification question: Is the current DisneySea in Toyko 20 or 30 miles inland from the coast? Are the temperatures similar to Anaheim? I am not sure if a aquatic theme park would do as well so far from the water. I think that is the key to Sea World's success, and isn't the relative proximity to Sea World a problem?
I love these threads that give the negative nillies another chance to complain and hypothozise and spend time on ideas with no real solutions.
