You can get very creative when owning a smaller high demand resort plus other points. You can reserve an entire trip (or portion of it) with the high demand points at 11 months out then at 7 months, book additional or replacement components with the other points. Another approach is to book the front end of a trip at 11 months then as the 7 month window approaches, book the first days with the other points and take the freed up high demand points and book the back end days. Essentially the walking idea but at the 7 month window and using non home resort points at the very end of the home resort window. While a little extra aggravation, these options have the advantage of either potentially booking a trip at the high demand resort for more points than you could get together banking/borrowing for the smaller high demand contract and/or allow you to work more with current UY points to minimize the risks associated with using banked/borrowed points. While not directly related, these type of approaches can be used to work with holding account points as well. Just remember that it's usually a good idea to book something at 11 months so you'll have a place to stay even if you have to move resorts or stay at a non preferred location.
