I think that from the point of view of the non-local tourist, Showpass is going to be fnorked beyond confabulation.
Fastpass and Showpass are two more ways that Disney positions DLR as primarily a local park, and markets it primarily to locals. It's a perfect marriage.
For Disney and for locals, that is.
For tourists, not so much. But then, they're not the audience Disney is chasing.
Now, I'm not saying Disney doesn't want tourists. I am saying that everything Disney has done in the area of ticket sales and promotions in the last decade (more like the last 15 years) advantages locals. It's obvious that Disney consider locals as their prime DLR demographic.
And that is what Fastpass and Showpass are all about
: advantaging locals.
The people who say Fastpass is "easy to figure out" are inevitably frequent visitors (most likely AP holders) who have already figured it out, use it to their advantage, and are loath to give it up. Of course
they're going to want Showpass -- it gives them the advantage! Big hairy disclaimer: the above is no criticism of local DLR visitors or AP-holders.
Disney has been working its Mighty Marketing Machine on overtime to attract your business, and you have every right as consumers to take advantage of it!
