You'll have to be in a lockoff two bedroom villa for the first nights. Then request to be blocked into the studio portion for the last nights. Have them note both reservations on the other. When you arrive, check to see if you are blocked into the same studio. We did this a few years ago at OKW, except it was the other way around. We arrived and were in a one bedroom, then moved to a two bedroom for our last four nights. They were able to do this for us. But it did delay our moving in for the first night because the guests in that villa didn't leave until nearly 4PM and were asked to leave. They had wanted to self extend.
