FD is definitely a shell game.
I have definitive proof from planning our upcoming trip over Christmas.
When priced out on Disney's site, total package was $4500, no dining.
When I reached out to an infamous TA, total package was $3300, no dining, $4500, with dining.
So, I could have moved our trip to start on the 21st, if thats going to be the last day of FD again this year, and hold out for FD, but I'd pay $4500, and probably even more since sometimes you have to upgrade to a preferred room.
Disney could just offer the package for $3300 without dining, like the TA was able to do, but no, they force you into FD, and everyone celebrates.....
