As a regular camper at Fort Wilderness, I have an opinion on this proposed policy:
This proposed change affects those who book a "throwaway" on-property reservation to get the 60+10 FP window and, after getting those, cancel the reservation (typically within 30 days or arrival). Emphasis here is on "book-then-later-cancel". The waived parking fees and Magic Bands costs are variable (time of year for the room/site and number of people in party for the MBs) but I believe that throwaway rooms get cancelled more often then kept/held onto and sitting empty. Way more. You book it and paid for it and keep it and want it to sit empty or use it/perks at the resort for day use only? More power to you. You paid for yours like I paid for mine.
The problem with the "book-then-later-cancel" is that one night kept me from booking a week at the campground well in advance and when you cancel it within 30 days, it's too late for me to make plans, schedule time off from work, and book a trip to the Mouse. I daresay most people don't plan and book their trip within 30 days of arrival ("most"). So the cancelled site sit unused because its too close to a possible arrival date to make plans to use it.
The WDWNT link language in the post announcing this proposed change is revealing. "Loophole". "Fraudulent". Yes it was a loophole that was exploited because it was allowed and not explicitly restricted. Very few people stumbled into this situation by accident though.
I call this a step in the right direction.

PS - and a minimum stay requirement would be the next "right step". Oh I've booked a one night reservation when I had a 5 night already and wanted to get a 6th night and the stupid system wouldn't let me. If you have consecutive nights and want more, you should be allowed. But that may be asking too much of Disney's IT system.
