When I first pulled up my first thought was "tacky" thanks to all the bright colors in the lobby of the hotel and my room. However, after a few hours The Saguaro grew on me.
There is a fun pool area, which sadly I wasn't in Scottsdale long enough to enjoy. There's a fabulous gym filled with state-of-the-art equipment. And the hotel staff was as cherry and bright as the colors throughout the hotel. They also offered me bottles of water about every 2 minutes, which was much appreciated in the hot Phoenix weather.
We scored a pretty awesome rate of $125/night. For that I'd definitely book The Saguaro again. You won't get the resort experience that you'll get at some other hotels in Scottsdale, but definitely a fun and cheerful place to stay.
