Only owners at a resort have access at 11 months. Given that limited audience, it won't be terribly hard for owners to get in most times of the year. Certainly December will be hard (as it is everywhere), and there will be a smattering of other sought-after dates. But given the inability to oversell a resort, it's pretty much impossible for 11-month reservations to be difficult year-round.
At 7 months, it's a different story. But not too much different than the story we've heard before.
There WILL be availability at 7 months--there's no question of that. As is the case at all other resorts, owners of KTV will not be consistently booking at their Home resort more than 8 months out year-round.
Some won't book all of their points that early. Some will book other resorts. Some will bank points. Some will allow points to expire unused.
So there will be rooms available at 7 months. But a likely high demand for KTV among non-owners means that those rooms will be booked quickly by non-owners.
The byproduct of a resort with high demand is that it will reduce demand elsewhere. Most seem to be arguing that all of the resorts currently under development (Contemporary, Grand Californian, AKV Kidani and even Hawaii) will be highly sought-after by members. If that's true, it should lighten the load on other resorts like the BoardWalk and Beach Club.
