I stayed here during the past spring training season, and this is a great bargain for the price. The resort is a dot away from Phoenix but it seems like you're in a country of your own! By luck, the butte is surrounded by a freeway and Anaheim Angels stadium facility that barricades itself from the surrounding neighborhoods. And so, it almost gives off an "island feel" to the resort.
It's a Marriot Tier 5 (i think) but could be bumped up, I think.
