This sentiment has recently been said multiple times on this forum.  I disagree.
As with now, people who studied WDW/planned/prebooked had an advantage over those who didn't know to prebook/research WDW ahead of time, but that is still true today.
I found the parks very enjoyable in that time period.  I took advantage of some amazing bounce back offers and other deals in that era.  Anecdotal, but the Disney forums were considerably more lighthearted/positive than they are today.  When the pandemic hit, and WDW closed, I missed out on a fabulous bounceback booking.
One of my best WDW hotel stays ever occurred in 2019 at the brand new Grand Destino.  Everything about that hotel stay was perfect.  Our mousekeeper even went so far as to decorate our bathroom with a paper rose.  The service was impeccable from the moment I pulled up to the curb to the time I checked out.
That was also the era of EMH for all onsite hotel guests.  I strongly miss the fun of going to MK until 3am w/just a regular park ticket.  If you knew anything about the ebb and flow of crowds, and got slightly lucky, then it was fairly often possible to make excellent use of EMH to ride e-rides, especially in MK.
I also much prefer the hotel room decor from that era over what WDW has now: the Contemporary, Wilderness Lodge, Grand Floridian, Caribbean Beach, Coronado, etc. The fold down beds at the values are an improvement, but the rest of the in-room decor is not nearly as fun as it once was.
