I recently ate at Whispering Canyon restaurant in Copper Creek and it stayed open until 9 or 10, so I think resort restaurants with reservations stay open later. But I was staying at Animal Kingdom Villas and neither quick service dining restaurants were open at Kidani Village or Jambo house, so those resorts were left without food options at all. I would assume the hotels that have open quick-service are closing earlier, but I don’t know that for sure. I think most bars/restaurants in Disney springs close Sometime before midnight as of right now
