You will get a million answers to this one. I have a feeling, for some people such as ourselves, once you watch it form a certain spot, it becomes "your spot" for sentimental reasons. We always watch from just in front of the Japanese restaurant, standing up on the stairs. Not a popular spot but it isn't usually crowded. Then we walk the OPPOSITE way around the World Showcase (toward Italy) to let the crowds thin out at the busses.
