I don't think free dining is scam either. The only time any kind of room discount is better than free dining is if it is only 2 ppl and you are staying in a deluxe room that is more than $300 a night and you get a 35% off room discount. Or if you are a person who hates the dining plan and couldn't care less how much it saves you. You don't want it and you will use a room discount every time.
When all 5 of us go and we get free dining with all 5 of us being considered adults it saves us a ton of money.
Both times we have stayed in a family suite at ASMu for around $240 a night. a 10% room discount (which is usually all you get at a value) would have saved us $24.
Getting free QSDP for 5 adults saved us $200 a day.
Even when we took the free QSDP and upgraded it to the
DDP it still saved us a ton of money. There is never going to be any kind of room discount that beats that free dining savings.
Both of our trips we had booked with no discount. rack rate. because we had picked our dates and that is when we were going, discount or no discount. So when the free dining came out that applied to our dates of the trip we already had booked and paid for, it was a genuine free dining plan with plenty of free food that didn't cost us a dime more than what we already paid for our package.
Some ppl think it is a crime to pay rack rate for a room no matter how much free dining would save you. They would rather take $40 a day off their room and spend $200 a day paying for their food out of pocket. You will never convince those ppl that free dining is a better deal.
But I also know there are a ton of ppl who DO plan when they take their vacation around free dining dates. Most of those ppl will post on here and say they can't even go to Disney unless they get free dining. So those ppl will absolutely change around dates to make sure they get free dining.
But since they only allow so many rooms at each resort to be sold using the free dining promo I really don't think it will swell park crowds beyond what it would have already been. September is a slower month because it is heavy hurricane season with a lot of rain, high heat and humidity. So they need to lure ppl in during that month.
