Early next year, you decide you want to arrive on a different date. Your modified reservation will be at whatever the rate is for new reservations and it will subject to whatever availability there is at that point. You cannot depend on being able to move your reservation to a new date range at the same hotel for the same room type at the same rate.
It's the same with points reservations.
Thanks so much for the quick confirmation. I'm more familiar with flights with miles, and several airlines (like American Airlines) allow you to change the dates of flights without re-calculating the number of miles necessary (as long as space is available). I wasn't sure if any hotel programs operated in the same way. Now that I have this information I'll work to book on specific dates that I know I won't have to edit later.
