The entrance of a theme park is the opening statement. Everything the park is themed to should be explained in the entrance area. Disneyland has Main Street, U.S.A. which brings a nostalgic vision of days gone by. Disney's Animal Kingdom is a lush jungle, distancing you from the human world and bringing nature to the forefront. At then end of these opening statements is the topic sentence, the central icon of the park. Either a fairy tale castle or a old fashioned movie palace, or even a gigantic tree.
In 1999, Epcot started a program called Leave a Legacy. For a fee, guests could have words or images laser embossed in a small square on a large metal sheet. These sheets were then attached to large stone blocks. This area of blocks was called the Legacy Plaza, which formed the main entrance for Epcot. Many people dislike the large stone monoliths, stating they resemble a graveyard or war memorial. While removing them would be the best option to most, there still is the matter of the people who paid for there square. I would guess there was a legal agreement that those images would be left up for a certain amount of time, if not indefinitely, and that legal agreement must be honored. So, the best solution is to build the opening statement of EPCOT around these images and monoliths.
The Living Legacy Plaza
The first real solution to the Legacy Plaza is to add greenery around the stone monoliths. The lack of natural elements is the main weakness; flowers would add more visual interest to the plaza. As living beings, we crave living things around us. Its accepted that even a small silk plant can improve a cramped office space (which is why they sell cheap silk plants at OfficeMax). One of the best views the Legacy Plaza is during the flower and garden festival, when there are large topiary and flowers around the plaza. The picture below shows some plants that could be used around the monoliths.
While adding plants to the monolith would make the plaza more aesthetically pleasing, it is still just a slightly prettier collection of war memorials. The real solution to the artistic wrongness of the Legacy Plaza is to redefine it in regards to the rest of EPCOT. EPCOT is about the world, and how the world has grown and evolved together into a diverse tapestry.
Lining the pavement through the plaza would be a series of small indentations, creating a pattern along the path around the main flowerbed. There would be 4.5 billion dots representing the population of the world in the 1980's. Using the opening year's population makes the addition feel more like part of the original park. These little dots would simply be an added feature to the pavement during the day, but at night they would transform into a dazzling array of fiber optic lights.
These lights would replace the older light panels found further in the park. While the other lights are popular, they don't really connect with the rest of the architecture. These newer lights would feel like they belong, and would tie in to the overall idea of EPCOT.
The Ultimate Idea
All of these little adjustments would simply make the entrance to the park more interesting for the average park goer. More greenery and interesting little lights. However, these elements add a new layer of story to this portion of the park, something that would entice the fans who notice and appreciate the thousands of small touches that go into Disney Parks all the time.
