DVC member since the 90s, so this benefits me, but I truly don't understand rack rate pricing for Disney hotels anymore. I've been lucky to stay at some of the nicest hotels around the world and Disney deluxe resorts are priced at least 2X any comparable resort even in very high cost international cities.
When you have someone in a bubble (resort, ticket, food/drinks, merch) you typically do not overcharge for every single piece of the puzzle. You may lead people in with lower resort pricing, and then make up for it with the tickets or food or Merch. Disney is one of the few businesses in the world lucky enough to get away with this (Apple being another.) I'm surprised at the number of people willing to pay that much per night.
Honestly at current pricing, Disney should be adding a lot more than just extended evening hours to deluxe/DVC.
