Yeah Blahnde...you threw us a curve on this one. I read your post, then that of the OP again, then your post again, then the O.P.'s yet again and my head started spinning. When you said, "Carefully worded," I just thought there must be something in your post that I was missing, so I dropped it. Could you explain? The O.P. said that it was necessary to pay twice when changing, the pp's agreed, then you said that paying twice isn't necessary.
It should not cost you $95 to delete a day or cancel the reservation, but the points for that day or cancelled ressie will be "Reservation Points," meaning that they would have to be used within the Disney Collection, Cruise, or Adventures by Disney in the future, and that reservation will cost another $95.
So even if, as Blahnde suggests, you could add a day for free (using more points) then later cancel a day to "reverse walk" the reservation, it would be of no advantage, unless you planned to use another Disney Collection venue in the future and pay another $95 fee to do so. However, it is very likely that they would charge the $95 to add a day, as it is a "new" Disney Collection reservation with "new" points transferred from DVC to Disney.
Dudelydude: Sorry I confused you! As ChuckS said you can alter a reservation without paying an additional fee and my post was intended to point this out. BEASLYBOO was incorrect, not me.
The reason I was being "careful" is that I had posted much more specific directions to the opening poster which resulted in my post being removed and my hand being slapped because of my deliberate attempt to subvert fees ... and because I swore incorrectly! So now you know why I was being careful to get my point across, while not getting permanently banned!
Unfortunately it meant that I was not as clear as I would have liked to have been since I didn't want to cross the line ... again! Of course ChuckS said what I couldn't since he pointed out the one flaw in my theory: the conversion to "reservation points." I stand by the idea, though, if there is any intention to do another trade-out where those "reservation points" could be used.
