Firstly, I was not trolling at all, it was a genuine question. And it seems that someone finally hit the nail on the head with the Earful tower being the original park icon and not the theater, which was just the "weenie" at the end of the main street there. If memory serves the dreadful hat was built around roughly the same time as the horrendous wand that used to dangle over the top of Spaceship Earth... And I point to that wand as justification for a petition... I may be wrong, but my impression has always been that the general public opinion of the wand was the justification for finally tearing it down.
As to the monorail issue... every time this comes up people cite the figures relating to the construction of the Las Vegas monorail, and while it is the same ALWEG technology, the costs of two installations and systems are not likely to be related at all... Firstly the Las Vegas monorail construction and expansion required land to be purchased, but the land at WDW is already owned. With the Vegas monorail there were multiple stages of city board and ordinance review, each round of which cost millions of dollars... seeing as WDW owns the Reedy Creek Improvement District and writes it's own codes, I don't really see this being an issue. As to the WDW monorail not being a money-maker you're missing a couple of key issues... firstly, they DO in fact charge for it's use, even though the hotels are based on three tiers, (value, moderate, deluxe) the deluxe tier is actually split into monorail loop prices and non-loop prices. You'll notice a stay at the monorail loop hotels will cost you considerably more. A monorail expansion wouldn't necessarily need to go everywhere on property, from a pricing perspective connecting AK and DHS and one value resort and one moderate resort would make sense I think. You could build a station between Pop Century and Art of Animation, and perhaps a station at Port Orleans. A station at Downtown Disney might also make sense. You would then increase the price for staying at these new monorail loop resorts as is already the case with the existing loop resorts. The increased ease of access to Downtown Disney may also inspire more spending. You also need to consider the cost of operating all of those buses, the drivers, the maintenance, the fuel (the monorail is electric, to correct someone who mentioned otherwise). Additionally if Disney can show that their newly expanded and green monorail system takes buses off the road there are carbon credits to be had, which can be used to offset their taxes or can be sold. There are many angels to consider beyond simply the cost of installing a monorail in LasVegas.
Do I expect the CEO to personally read a petition signed by 100,000 people and respond? No of course not. But if you distribute the petition to every voting stockholder they might start asking about this stuff at stockholders meetings. Additionally I imagine there are people in parks management and imagineering that wouldn't might having a bit of public opinion on paper to use as ammunition the next time they make a proposal.
