If you’re not dead set on staying at a Disney-owned hotel, but still want to be on Disney property, I’d 100% recommend the Waldorf or the JW Marriott next door.
You’re often paying around the same price, or even less, than the Contemporary, Grand Floridian, or Polynesian, while getting a noticeably more upscale property. The rooms are nicer, the service feels more refined, and they offer basic luxury amenities that Disney’s deluxe resorts usually lack: like room service, turndown service, in-room features like, robes, little chocolates, etc. Poolside cocktail service.
The bars, restaurants, pools, and hotel grounds also feel much more geared towards adults. You still get transportation to the parks, so you’re not giving up much in terms of convenience. Also way less kids running around.
I find it crazy that Disney gets away with charging Ritz & Waldorf prices while not providing the same level of experience
