I see another problem with your plan.
Owners can only book 7 consecutive nights when the 11-month window opens. After that, they have to wait to add additional nights. An agency won't even contact the owners on their list until all the nights needed for your reservation can be booked. So, for a 9-10 day stay, you're looking at 8-9 nights. This means that instead of trying to get your Std. View studio at 11 months from check in date, they won't even try until 11-months plus 1-2 days. Instead of trying for that reservation on 02/15/19 for a stay that begins on 01/15/20, a request won't be sent to any BWV owners until 02/17/20 in order to get all 9 nights.
MLK Day in the USA will be celebrated on Monday, Jan 20th. Many school are off that day and around here, at least, the Friday before (01/17/20) is a professional day (no students). It's not going to be as quiet at DVC as you might think. A 4-day weekend, combined with low point requirements and a newly-opened SW:GE is going to make getting a reservation for those nights difficult.
