Sorry I do not agree with the grounds at any of those resorts being better they are far smaller compared to the D Deluxe... Where are is the Tiki torch lighting ceremony, The boat rentals, The bike rentals and paths, The spa, The Beach, The fire Pits, the Marshmallow roasts, The movie under the stars, The golf Courses... go into the GF and lets not forget it has the only true 5 star eatery in Florida and Grand one.. Pool activities they have a pool party everyday with music, games and Giveaways, Pools ahhh Stormalong bay
What you mention are not Amenities they are services and Disney will do all of that for a fee CR certainly has private Cabana rentals... No one has ever said no to me at Disney??? in fact last time I Stayed at AK one of the greeters took my son by the hand and walked us to the check in desk

if you would like to pony up Disney will provide any service you would like. There are people who go on vacation and are willing to pay for location and service and the better rooms Disney offers at the Deluxe resorts... as you can see from the list above you will have different types of people who will stay at Disney Deluxe and there are enough people in the world who will pay for Grand one which does include a Butler and eat at V & A whit out a second thought.....
Lets not forget the resort fees, parking fees and mandatory tips you need to pay at a lot of other resorts with a low starting price... Atlantis for example you can easily pay as much in all the fees as the room costs... but of course Atlantis did it different as you can get the same room in a different location with a much higher level of service for a fee... and then of course the rooms and service for those willing to Pony up the big $.
I do not understand why you talk of all these things when you are staying at the Swan and Dolphin for a location but they pal in comparison To a Disney resort in respect to grounds, Lobby, and Amenities.. Services sorry do not see it there.. not to mention they are true convention resorts... lets not forget the on top of the room rate they have a 23 a day resort fee and 17 parking fee.
The rest of the resorts you mention are timeshares and the first thing you get asked when you walk in is if you would like to buy...
I enjoy my stays at Disney Deluxe resorts for what they are.. stayed in them before I owned DVC and will if I sell it.. They have never done me wrong.. that is not to say they are perfect as they are by far not but they have always settled any short comings faster than 99% of any other brand I have stayed at. Now if you would like to have a nicer room at Disney on the cheap by or rent DVC for a 1 or two bedroom.. I can tell you The Master bath at the newer DVC resorts is bigger than a studio at the values and amazing... You can also pay for nicer than those in the suites at any Disney Deluxe....
I had the pleasure of speaking with for hours a man form Canada whose company paid for him and his family for a presidential suite at AKL and I had the opportunity to see the inside... He was very impressed with it as was I... He had no complaints and a lot of Praise.. I would gather but am not certain he stays at a lot of very high Hotels in suites

Again if you are willing to pony up Disney will provide anything if you are price comparing then yes you can do better in Orlando minus location.... however there has always been three rules in real estate... Location Location Location and Disney has it and they DO charge for it as would any business. I like my location and I am willing to pay for it some are not. Yes my bed in a studio may not be as comfortable as in other resorts but I can tell you in a one or two bedroom it is... and I enjoy a bathroom that simply amazing.
