My friends and I were in Phoenix for business trips for 3 nights (Tues-Friday). We booked via corporate rate at $125/night without tax but that was really it...real corporate rate (e.g nothing was included except free wifi). We asked about waterpark and it would cost us $40 per each entrance/person. Breakfast was also additional to the rate...etc. I stayed for a total of 3 nights for a net cost of around $450 (including tax).
While the room was had was great (there was a separate living room from the bathroom) and the place was spacious, the place was a bit too far apart (e.g. if you don't have a car, good luck walking!). There was, however, no refrigerator in our room (except the mini bar which required a key to open). A swimming pool in our section was very small and didn't look that clean. At night, our room section was a bit deserted and dark, so I was slightly concerned that if someone were to enter the room without permission, I don't think the hotel people would know. Both my friend and I had our separate rooms, so we both just end up just shutting the blinds in our own rooms completely.
Overall, the room was spacious and the decoration was ok. For the value though, you might be better off at Marriott or elsewhere.
