To me, the most relaxing deluxe resort is the Wilderness Lodge. Each can stake its claim for its own reasons, but let me tell you why I think WL is the winner.
First, the great open lobby is full of big, comfortable plush chairs and a huge fire place. I have hung out here and almost fallen asleep in those chairs, waiting for my reservation to be called at Whispering Canyon Cafe.
Speaking of restaurants, Whispering Canyon and Artists Point are both soothing names. I can't say Whispering Canyon is all that relaxing a place to eat (anyone who's eaten there can understand).
The outdoors areas that go back around the big pool and then down to the docks where you can load into a boat for water transportation is also relaxing to me. The surrounding pines give a feeling of seclusion and quiet. There is no monorail constantly swishing through the property (I love the monorail, btw) so there is less busy activity of people coming and going. This is a feature WL shares with the Animal Kingdom Lodge, another very relaxing deluxe resort.
Finally, to my ears, the WL is a quieter resort than the other deluxes. The Contemporary is visually busy and the constant coming and going of the monorail through the hotel and the people coming and going makes this the least relaxing to me. The Polynesian - which I love - also seems to have more people coming and going all the time and maybe has the most loud young children (which is fine), and while I can certainly relax there, other deluxes are more relaxing in my opinion. The Grand Floridian can come across as a bit stuffy. I imagine myself donning a white linen suit and straw hat and sipping bourbons in the lobby one day - a bit too formal for the title of "most relaxing," I think. The Boardwalk is another busy area with a constant hubub going.
The two most relaxing to me are Wilderness Lodge and Animal Kingdom Lodge. I give the nod to WL based on its accomodating lobby and available but tucked away water transportation service. :wave:
