FDP was only instituted after hurricanes hit the prior years & the rooms were begging to be filled, not so much a 'perc' as a promo
Disney has generally offered promotional rates after the Florida kids go back to school and before the Columbus Day weekend; middle of August through September. FDP replaced deeply discounted resort rates during the same time period. The current DDP started in 2005.
Discounts during the "hurricane" season isn't anything new.
edited to add--The fact is the DJ played music that at least some parents may have an issue with. That's useful information. Many parents may not have a problem. Others will. A review is useful if it gives reasons. People reading the review can decide if those reasons apply to them. I'm not sure why so many people are attacking the review.
