100% agree with this. I assume they will have to heavily discount, but even then...
I wish I understood what they are doing here (besides the obvious of trying to suck as much money out of people as they possibly can). I remember looking at WDW tickets for the first time about a decade ago, and thinking how cleverly they were priced. The first couple of days were crazy expensive (well, it seemed that way at the time), and then after that the incremental per-day increase dropped dramatically. So you were encouraged to buy a longer ticket than you really wanted or needed, and maybe wouldn't even use some of the days you paid for, or would spend fewer hours per day in the parks. Now they seem to be going in totally the opposite direction. People have already pointed out how single day tickets could actually cost less per day than multi-day tickets in some situations, and if the numbers we're seeing posted hold, it looks like some AP options will be cheaper than the longer multi-day hoppers. Assuming $60+ for hoppers, a 5-day hopper is going to be near $580, compared to $589 for the gold AP (for those who are eligible). You've got to figure that 6-day or longer hoppers will actually cost more than the gold AP at that rate. I'm sure they know exactly what they are doing (and why!) but on the surface it doesn't seem to make much sense.
I'm strongly tempted to buy another set of gold APs for my family now, but I already have a handful of non-expiring 5 day tickets, and we have no firm plans to go back after our upcoming March trip. It's hard to justify a nearly $2400 expense (almost $3k in my currency) for an unspecified future date. Our kids keep getting older (go figure), and by the time we've used the tickets we have, maybe they won't be so interested in going to Disney, or they'll want to spend some time at Universal. The way ticket prices are going, they are quickly eliminating the cost advantage of staying exclusively at Disney, so there would be no reason not to split the tickets and spend a couple days at Universal instead!
