I stay at AllStars sometimes. No way I would be drawn to do a Table Service there. I get capacity problems but I've been at the resorts during fairly sold out times ... busy? yes but not unmanageable. Seems like the balance comes from folks eating at the parks and Disney Springs.
Maybe the tent city buffet in the CBR parking lot gave them the idea. OR maybe they are thinking about the shorter park hours becoming more a thing, guests are returning to resorts (especially AllStars). I think I am looking at it more as the result of something negative happening rather than an added experience.
