Seems like a lot of interest in this property and quite a bit of speculation based on pictures that are available, so here's a rather lengthy review that addresses some of comments from recent posts. I was at WDW about three weeks ago - I also posted a review earlier in this thread addressing some of the comments that were being discussed at that time.
I don't believe the picture from TripAdvisor is reflective of the average 1 BR deluxe - you can see it has two windows, so its an end unit and that might be a slightly different design. We had a 2BR L/O and the deluxe side was in the interior of the building. My spouse and I both agreed that the design of the deluxe unit was far better at WDW than at other resorts. Its larger (I believe about 75 sq ft more than most others), there is a full size fridge, the dining table is larger and there is MUCH better light exposure. In addition to the windows in the living area, the placement of the bathroom and bedroom allow light to enter the living area from the patio off the bedroom. I doubt either of our units had the "outlet situation" identified in the picture - if that was in our units, we never noticed it.
The premium side is slightly smaller and the fireplace sort of sticks into the middle of the room. While we were a little concerned about the design when we first arrived, we decided by the end of the trip that the changes were not problematic. The slightly smaller size compared to other resorts was a non-issue, the placement of the fireplace was a mild visual annoyance more than anything else.
There is no "fancy waterfall" as depicted in the early artists rendering. The second rendering is pretty close the actual design. The pictures look very stark compared to the rendering because of 1) intense sun vs. the soft palate of the rendering and 2) the lack of time to allow the landscaping to mature. From pictures it looks like a lot of concrete walls - when you are there, you can see most of these walls have climbing vines planted that will grow in and greatly soften the look of the walls. What probably would be more concerning to guests, which you can't see from the renderings or the pictures, is that there is a service road (used primarily by carts, but also the occasional full size commercial vehicle) running right along the pool area between the pools and the golf course. It does detract from the resort feel having a concrete road running through the property.
The quality of the villas themselves are really not significantly different than any other Westin properties. The color scheme appears to be a concern for some people - we didn't even think twice about it when we were there. And I would say the couch in the living room was much more comfortable than other villas (WPORV comes to mind as being particularly uncomfortable).
What stood out to me is that the land upon which they had available to build is long and narrow and since the golf course has been there for several years, not much could be done about that (I'm sure this is one of the reasons the service road issue above was unavoidable). What this will mean is than the next phase that will be built will be a significant distance from the clubhouse, however, two additional pool areas are planned for future phases - one adult pool area and another family pool area with its own waterslide. These will not be side-by-side like they are at the main clubhouse - they will have their own "cluster" of villas around them.
WDW is different than WMH, no question. Some will prefer WMH, some will prefer WDW and it all depends on what you are looking for in a property. Not having the hotel combined with the villas changes the vibe of the resort. There is no onsite spa and the golf course is not officially part of the resort, so (at least for now) there is no cart service that will pick you up at your villa and take you to the clubhouse. You have to drive your car or carry your bag about 1/4 mile. I asked a staff person if that was going to change and he didn't know.
Finally, a couple of comments about the TripAdvisor posts. One stated that parking wasn't free - not sure where that come from since it was free when we were there and there was never an attendant at the gate (you access the parking areas with your room card). I also sensed that some of the posts were from people who were expecting that it would feel like a Westin hotel and thus were disappointed. I think everyone here understands the difference between a Westin hotels and Westin villas.
I didn't really take pictures for sharing purposes, but the link below will give you another glimpse of the inside of the units, the view from our deck and the adult pool area. We've stayed at several of the SVN resorts, so have a pretty good basis for comparisons and all in all, we were quite happy with WDW at this stage in its development. Our kids will prefer WDW over WMH because the pool amenities are better at WDW. For golfers, having the course amenities integrated with the resort is nicer at WMH, and while both resorts have excellent 36 hole tracks, I would possibly give Desert Willow a slight edge for quality of play. For those looking for a more complete resort experience, WMH will probably be a better choice. And if you like the grass and landscaping at WMH, you won't find that at WDW. Its very much desert decor and foliage - the only grass you will find is on the golf course.
