I don't think Dapper Dan was trying to argue that WDW is better than DLR because of its beaches, trails, boating, etc. - he was, in a roundabout way, making the point that this 1:1, A>B binary type comparison is silly. WDW and DLR are two different animals. I would agree - and I think most people here would agree - that for what it is, DLR at the moment offers a higher quality experience than WDW, but they are two very different things and judging them on the same scale misses the two very different cultures/audiences/purposes of the resorts.
I would not follow from there, as Supermatt70 does, that WDW in its current state is ideal for a particular audience and/or meeting its goals as a resort. I think that WDW falls woefully short in many areas. But I come to that conclusion by comparing WDW to its own potential, purpose, and vision; not by comparing it to DLR. That would be absurd, and I think that was Dapper Dan's primary point.
(And for the record, I do think there are some categories where WDW - even in its current state - equals or far surpasses DLR. I wrote extensively on that in another thread.)
