Since WDW vets are so accustomed to the larger size of WDW, it does not seem to bother them very much how far apart everything is at WDW. Yes, you are in a Disney bubble. But it is a very
big bubble and you feel (well, at least
I feel) very far from the parks when I am at a WDW hotel or DTD. This does not even speak to the off-site hotels which are even farther away.
At DLR the bubble is smaller and you
can see the city so the bubble is not as immersive. BUT, you have many hotel choices that are right there across the street from the parks. Or, better yet, the GCH which is connected to DCA. So you feel closer to the parks because you
are closer to the parks.
It is my observation that WDW vets value the overall resort experience more, and that DLR vets value the inside the parks experience more.
What I do is just switch hats and expectations when I go from one resort to the other. I know WDW will be more immersive but I will be sitting on buses a lot. I know DLR will be less immersive but I will be able to spend a higher percentage of my day inside the parks - and can have a much more flexible, unplanned experience - since everything is so close.
As soon as someone starts saying that one of these experiences is better than the other, it really gets to how they prefer (or have come to expect, based on experience) the resort level focus vs. park level focus. And often, this has been conditioned from many previous trips and a gut level feeling on how visiting a Disney resort "should" be.
