The point wasn't that they didn't understand the reason. The point was that they are charging the same thing ... but providing less. Personally, I don't care if housekeeping is coming every day or not, but if they aren't, then the overall room rate should be discounted, or guests should automatically get the "no housekeeping" gift cards they received previously for no housekeeping.
That said, I haven't stayed or tried to stay in a Disney-proper resort yet, so maybe they are discounting the rooms sufficiently to balance the fewer amenities. We did stay at an "on site" non-Disney hotels (so that we could get park reservations since AP reservations were non-existent) this past weekend and they are all still charging the same resort fees when they too are not providing the same amenities that those fees were suppose to cover (shuttle service, as an example). However, the room rates themselves are discounted from "normal" for no housekeeping.
I was able to get the park ressies I wanted for our next trip in a few weeks so we'll be staying offsite next time.
