I believe that weenie's and icons are two completely different things. An Icon is the park identity and for most of it's existence the earfful water tower was the Icon, later it kinda of became the Big A. Hat. Now there is no official Icon for that park, but, I'm sure we will find out what they chose once the park is renamed and reopened. Weenie's on the other hand are thing that draw you to a certain area of the park. Those would be the theater and the Tower of Terror. There are other minor ones as well, but, mostly it is that. Now, an Icon can also be a Weenie, like The Castle in MK, Spaceship Earth in Epcot and the Tree of Life in AK. But, those are more the exceptions, then the rule.
