Judging by the odd way the press has jumped on the story lately, and poking around at various folks locally in Orlando, this scheme (maybe not exactly as laid out in the survey, but close) may be coming MUCH sooner (as in next month or July) than I thought -- all very much rumor. This new system may just be for
Disneyland or Orlando, or possibly both. And yes it will be the biggest single price increase in history. (Although very much masked by the tiers )
If it does happen, tickets bought before the changeover would be honored, and non-expiring tickets that still exist would still be honored, anything brand new after that day would be on this new craziness. The marketing speak term for it is "surge pricing", and would being sold as a way to protect you from the crowds. (Ala hoping your mind would link it to protection from "storm surge" flooding-- or other bad types of surges)
