Yes, it is.... except at certain locations.
1) CA Grill still EXCELLENT - but stay off the DDP.
2) Narcoosee's still EXCELENT - but stay off the DDP.
3) Citrico's still EXCELLENT - but stay off the DDP.
4) Disney Springs a total disaster. All buildings, no food.
5) In Park anything - Park food
.
Options: If you qualify? Consider TIW. This gets you the EXCELLENT non-Disney owned Restaurants at Swan/Dolphin. Shula's and Il Mulino.
Avoid Blue Zoo - it's a walking disaster. Great building & Service - rotten food.
Also consider booking GREAT off site Restaurants like Bull & Bear, Capa. There are more... We intend to cab to Morton's Steak House next trip.
As the food at WDW degrades? Just a suggestion - don't eat it. Hit those wonderful NON Disney Restaurants. Some on site, some off site. Really - a cab driver does not care
.
So bottom line.... yes, WDW is loosing this. More and more, we go off site, or on site-non Disney owned, for great dining. The general formula? If it takes DDP, be suspicious.
All personal opinion - I'm not necessarily right, no one else is necessarily wrong.
