LOL. From the current resort launch location, it will only be ~ 0.8 miles to the farthest point of the Grand Floridian (the front portico of the DVC building), and only ~ 0.7 miles to walk to the main portico of the Grand Floridian. For comparison, that's less than an lap longer than the walk from the Grand Floridian main building over to the Grand Ceremonial House, which hundreds of people make every single day. And this distance is just shy of the length of the walk from EPCOT Center's security gates to the Mistukoshi.
If you have ever stayed at the Grand Floridian, left the Magic Kingdom at closing time, and seen the lines for the monorail and the resort launch, you would know that this walkway will get used a lot. And guests have wanted it for a long time.
