You'll have a decent chance of availability at 7 months at AKV or OKW in October, especially if your dates are a little flexible and you're not looking for a particularly lengthy stay. If you're looking for a specific whole week, I wouldn't count on it.
One thing that may be a complicating factor is refurbishments at both resorts. While nothing has been announced, based on the 7/14 schedule and prior work, AKV is due for a hard goods refurb in 2024ish and OKW is due for a soft goods in 2024/2025. Either of these would take inventory offline and make booking more difficult, if not unlikely.
