Well, we're still waiting for that inside rumor to actually happen. Next time someone has lunch with him in the Haunted Mansion restaurant, ask him when it's going to take place.
There's a difference between inside talk of what they may do and what they have definite plans to do. I'm sure raising rates to pay for the capital investment of the gondolas over and above the what the resorts have paid for bus service is something they have a definite plan for.
Getting back to 'tiers,' the 'tiers' designation is pretty useless as it is right now since there are huge swings in prices within each tier. You also need to know if the quoted cost from a value tier category is for a campground lot, a regular room, or a suite, and what its view is. Will that be $47/night or $247/night? When I select a tier on the WDW website for pricing, the result shows all just the resorts for that tier. But, when I input the dates, then bam!, tier designation is gone and I'm being shows all the resorts. Not to mention WDW keeps adding and moving around resort 'tiers' designations without any announcements (oh, hello Gateway Hotels, and the Swolphin and campgrounds are their own category now, and Good Neighbor...).
As far a rate increases, what if they went up 20%! For the basic Pop room at its usual $120 discounted rate, that would mean it would be $142. Which isn't too bad. I don't see the values jumping all the way up to what had traditionally been moderate pricing. But, just a guess on my part.
