When we spend thousands on this vacation, I don't want to have to wait more than 20 minutes to get a table, and I certainly don't want to have to go to several places before finding one that would work for our family. What a waste of valuable time.
Fair enough, but I have made many ADR's, and many times I've waited well over 20 minutes past our ADR to be seated. When WDW was less focused on ADR's, we usually only waited a few minutes to be seated. It is also worth adding, I try to follow the old guideline of arriving 15minutes before the ADR time.
One trip, we had ADR's at both 1900 Park fair- waited over an hour past our ADR time, and Grand Floridian Café- waited 50minutes past our ADR time two days later. After waiting that long, everyone was very hungry and cranky both days.
I can list quite a few times/places we were seated 20+minutes past our ADR time, and most of these it wasn't just once, but pretty regularly: 'Ohana, Be Our Guest, Boma, Sanaa, Crystal Palace, Cali Grill, 1900 Park Fare, Cinderella's RT, Liberty TT, Plaza, Tony's TS, Le Cellier, Tokyo Dining, La Hacienda de San Angel, San Angel Inn, Mama Melrose, Flying Fish, Narcoosee's (usually pretty good though), and Whispering Canyon Café.
For a number of years, we generally made 1 ADR per day, but about 2 years ago, we finally got really sick of being seated late and cut back. The last time we had an ADR at 'Ohana - in 2019-it was especially bad. The whole meal was a disaster. We were supposed to be seated at 6:30pm, and I thought that would be plenty early to see the fireworks. Worse case, I thought we'd probably get to see them from our table, but we were given one of the tables that had no view (near the bar area), and the meal was so delayed, they were well over before we were done. The whole meal was bad, including being served room temp meat - eww! At then end, our server made a mistake on our bill, over charging us. She never came back. We waited about 10minutes, and finally gave up, and just left the correct cash on the table.
So I hear you when you say waiting can be a problem. Yet, it is also why I made the comments I did earlier. Over the last 15 years, WDW was trending more and more towards us having to rush from one FP/ADR/timed thing to the next. That was my family's biggest complaint about WDW.
It was more and more us rushing to be on time, but then when we arrived- we'd arrive just to wait some more. On top of that, there were frequently ride breakdowns, monorail breakdowns, buses that didn't arrive. More and more it felt like WDW's service promises were empty.
