There is a significant difference between LL/Genie+ and FP+--With FP+ you could set up a ride schedule 2 months in advance, generally pick the times you wanted (not always possible), and plan your meals around those attractions. I used to be able to program a counterclockwise Magic Kingdom morning visit, have lunch, do 1 or 2 more rides/attractions and get back to the hotel for some important afternoon tippling. With LL/Genie+ every morning it's survival of the fittest as you compete against every guest at the same time, you don't get the times you want you get the times offered, and the times offered are often during your lunch/dinner which you planned months ago. It is a disaster (when it works).
That said, the park experience has been declining for years. That michael just noticed it is telling about his lack of knowledge about WDW despite being a very frequent visitor. Skimpflation and over crowding has been a problem at WDW for at least 10 years. Another park was needed years ago, not just new rides in existing parks or, even worse, repurposed rides.
Magic Kingdom opened 10-1-71
Epcot opened 10-1-82
HS opened 5-1-89
AK opened 4-22-98
It has been 24 years since WDW substantially expanded its park capacity. All the while WDW has built many hotels and DVC rooms. To the extent Michael is suggesting that the WDW is no longer what it was, he's about 10 years late.
