NEVER said I dont like it, just is silly to wait longer then ever 15 mins for a table, and yes Disney does have a 5 star restaurant.....Again if they can schedule a time for one to eat at 1PM then by all means they need to honor their end of getting them at a table within that time frame, zero excuses, every restaurant wants to turn a table as soon as they can, this is not unique to Disney...........
Victoria & Albert's, the 5 star restaurant, to my knowledge DOES operate as a traditional reservation. So there shouldn't be an issue with seating there. Again, Disney overbooks to accommodate more people (and account for no shows). So your wait time will vary because you're just being seated at the next available table - not one booked for you. As for turning tables over quickly, yes all restaurants want to, but this is heightened at Disney. Its why most TS restaurants have relatively small menus, basic food items, items prepared in advance, and many family style/buffet options. It gets people in and out.
And Disney could honestly reduce advance dining reservations by HALF when they release 6 months out and simply release more tables as ticket sales, weather forecasts, and even day of table flow data comes out. They could still fill tables with walk ups and delight people who planned and were lucky to get adrs in advance if they really wanted to.
How can they "release more tables"? Their capacity is capped at the number of tables each restaurant has. If they leave X number of tables to walk-up availability and stop accepting ADRs, then they may potentially lose out on guests because people will book elsewhere. That would be like if an airline stopped selling tickets even though the plane has 20 seats left, just in case someone showed up at the airport day-of.
There’s no reason for Disney to have ROUTINE extended waits for advanced reservations.
I don't think its that extreme. Do the popular restaurants run behind sometimes? Yes. Will larger groups maybe have a longer wait? Possibly, because there are fewer tables to accommodate them. Will people have to wait longer when restaurants are packed during
free dining and Christmas week? Its very possible. But to say the late seating is routine or consistent is an overstatement, IMO. I've never waited longer than 20 minutes to be seated, and I've often been seated earlier if I happened to check in earlier. Usually I am seated immediately or within a 5 minute window, which is about the time it takes for the seater to grab my ticket and menus before they call out my name. And we do eat at prime meal times. We maybe have an average one meal per trip that deviates from our typical experience, and its not even that extreme.
And I presume they DO use the data they have to project how many ADRs they can take per hour before they reach the tipping point of too many. As you mention, there are a lot of variables every day that would go into this projection - weather, ticket sales, guests who take forever to eat/loiter, etc etc. Even if they book to the exact number their analysis allows for, one of these variables skewing the wrong way can have a snowball effect, resulting in longer waits. It happens from time to time, but not ALL the time.
