Only 12 of the 24 tower studios have been declared into
DVC inventory. So half have been booked by DVC members and the other half have probably already been booked for cash.
While there are more regular studios, it's pretty unlikely that any remain available for this coming fall given that any member with qualified points could have booked them starting in February for September stays.
Or did you mean fall of 2022? If that's the case, neither DVC nor cash inventory is available to book for that time period as of today.
