Just came back from a Disney trip last week - stayed in the Treehouse Villas. Also, we stayed in the Congress park buildings this past January. Both visits were perfect as were the rooms. Like many others who have posted, don't really understand the hate this resort gets, but that's ok because there are rooms available at some pretty decent times of the year - so great for me and easy on the points!
I agree the transportation may not be ideal, but we drive to WDW and rideshare everywhere anyway. Observationally, the busses appear to run like clockwork and the few folks I spoke with seemed ok with the arrangement. The sprawling nature of the complex will certainly not be to everyone's taste, but I found the grounds relaxing and picturesque. As mentioned, I think the staff here is top-notch maybe only rivaled by the flagship GF resort.
One last thought, since I golf, I like hanging out for a cocktail or two by the pro-shop and they have some pretty decent merchandise - often they are running sales (yes, I said sales on Disney merch) - last week it was buy one and get a second for 50% off - this was on Adidas and Peter Millar Polos along with other brands - 2 Polos and 4 hats later - I was pretty happy to have stopped by.
