You can book up to 11 months in advance...in this case, it would be January 2005. Because you are looking at a peak travel time, you almost have to book at the 11 month window, thus you probably need to start looking to rent in earlier January. This will allow you to secure the transaction with someone and get it booked. If you have a particular resort you want to stay at, you will have to make sure the points you are renting are "home" points to that resort.
