I disagree completely, seriously, this has been rumored for so long it is pathetic.LOL ok. Paid FastPass is really inevitable. It just depends on what form it will be.
Seriously, the first time I heard the rumor of paid FP was around 1996 (yep before FP was introduced) and from credible sources and it has been repeated at least every two to three years since then. Again, nothing shows this to be more credible now than it was back then. And as I said there are plenty of reasons why this won't happen.
In case you are counting, that is over 20 years for this "credible rumor".
