The rooms you get through CRO are separate from those for members. Additional rooms may become available at 60 days or whatever, but there are ones you can book sooner.
I agree. We were told the same thing by CRO when we made our OKW reservations more than 6 months before our trip. They said that WDW holds a percentage of rooms from sales to be used by the general public that are available just as they are at any other WDW resort. If I were you, I'd call back and double check. You never know, CM's have been know to make mistakes and if nothing else, you could find out exactly when they do start booking the rooms reserved for the general public.
I've often read that it's tough to get reservations at the DVC properties, but when we started checking for our June trip, we had our choice of any of the Home Away From Home resorts. None were booked. I've also read that it's hard to get discounts on these rooms, but the codes that came out for our time frame always included them.
We chose OKW and we got a discount that made it less expensive to reserve through CRO than to rent points. Along with that we didn't have to pay to get maid service and we got CRO cancellation/reservation change policies.
In fact, less than 2 weeks before we were scheduled to leave, we had a change in plans that caused me to check about switching the type of villa we had. There was still availabilty at our resort had I needed to make the switch.
I think that sometimes the difficulty and exclusiveness of the Home Away From Home reservations is a bit overstated. At least that's what I found when I did our trip research.
As I said, if I were you, I'd call CRO back and get the details on exactly when you can make reservations. I really don't think you'll have any problems getting reservations through them, especially if you do so at the first available opportunity. Also, keep your eyes open for discount codes. At the time of year you're going, I'd be very surprised if there weren't some really nice discounts available.
