And I truly wouldn't worry about that time of year. Last year I made my ADR's in late Sept for our Jan 07 trip, and changed my mind over and over with many changes after that. I think I made changes up to 2 weeks prior to our trip and was always able to get the place, date and time I wanted. In fact I made both Boma and Ohana ADR's towards the end and when I called and said "something between 5 and 8 pm" thinking I'd be lucky if I got anything, the response was "ok, you can have 5, 515, 530, 545, 6" and so on..no problems at all.
