I don't know if it depends on the time of year, but I can tell you that booking around the 4th of July was really difficult! I would never do that again -- the resort was over 100% booked (one cast member told us it was at 105% but I have no way to verify that information). We wouldn't have done it this year except that was the only week all summer we could manage to get all the work and activity schedules to line up. I actually ended up borrowing some points from next year to book an extra couple of days to guarantee we ended up with the days we needed which will make planning our next big trip (in 2017) a little more difficult since I will have banked points I'll need to use or lose before our UY ends.
