Well, that's very interesting!
But I don't see how that would work. If they block hoppers, that would mean that only APs & 1-park tickets could get in. That wouldn't make a lot of sense.
I wonder if they're setting something up to offer a DCA-only ticket when SWL opens for people who still want that Disney fix but don't want to deal with the hellacious crowds at DL.
If they're in the works for having tiered multi-days, then a general price increase can't be far off. IIRC when they 'tiered' the single day tickets the 'value' day price was the previous price and the two higher tiers were more expensive.
