So while PIO was here we played around with some dates. While the 11 month mark was today (now yesterday), we were too busy running around DL to book anything. What we figured out was that booking a two bedroom lockoff for one week was only 18 more points than booking a one bedroom for five nights and a studio for one week.
With that in mind, I'd rather just book the lockoff even if we take off a couple days early. PIO and her family can enjoy the 1 bedroom part of the unit after we leave and that way we know we will be in close proximity to each other during out stay, but in separate units. And then they don't have to check in and out of the unit on the day we check out.
I'm going to book it (since there is no penalty) and then we'll work out the details as it gets closer!
