Exactly, I don't see how people think that restricting changes to only a certain number of times does anything but penalize low point owners or those with points tied up either banked or borrowed. Even if you don't what to do what you suggested here, you only need to walk a 7 night reservation every what 6 days to retain your room? So even if you restrict to three modifications without a flag you are still able to walk out a reservation just shy of three weeks in advance of the date you want. Now, if you are a lower point owner, or you need to work with banked or borrowed points which can complicate things, and you can't afford the points to walk a full 7 night reservation, then you would need to modify more often putting the lower point owners at a disadvantage, and allowing those with the points to do it to walk for a good period of time while only modifying the actual reservation a few times. I think some people mistakenly assume that you need to walk a reservation each day, and that it is therefore a lot of modifications, but if you have the points to walk a 7 night reservation it really isn't that many modifications, unless you want to book each day individually for some reason.
