We have stayed at the Poly 4 times in the last 2 years and have enjoyed it each time. I have always gone for the garden view becasue it was cheaper and on each visit requested a particular longhouse (tokelau, I like the quiet location). We have always had pleasant views of the pool, vegetation etc... I know there are some parking lot views thrown in there, but we have always lucked out.
The rooms at the Poly are fine, they are spacious and are well themed. Some bathrooms in certain longhouses are more spacious, if you check out tikimans website (there is a link at mousesavers.com), he runs through all the longhouses, pro's and cons and points out which ones have been renovated most recently etc.. I have always found it helpful. My only compaint is the tiny, tiny tv's in the gigantic armoirs!!!!
All in all the Poly is a winner and has the best (IMO)mid price restaurant of all the resorts (Kona Cafe). The pool is a dream and the location cannot be beat anywhere on property. Have fun, I wished I were going back
