Whats makes a good park layout?

When I think of my top ten favorite theme parks layout plays a role in how I rate them. The features of the park play a big part as well. But the overall layout plays a big part of the experience.
Old boardwalks and amusement parks, such as Cedar Point feature a long, narrow park plan, which reflects the nature of being on a coast. Cedar Point, which is over a hundred years of, still reflects this linear plan, as seen to the right.
When Disneyland opened Walt Disney created a new standard of park layouts. This model featured a center icon with different themed areas branching off from it. This model certainly reflects the park being themed and therefor revolving around a story, rather than the goal of amusement at older parks.
Today, this circular model derived from Disney is still used. Here is shown Universal Studio's Isand of Adventure park wchich opend in 1999. What will be the next revamp to the park layout? My thought is that it will be a model that reflects a storyline even more. Instead of symmetrical circle layouts it may be a single path which winds around the storyline of the park. It could be an experience completely revolving around one story.
