I had to travel to Phoenix at the last minute in mid-May, and instead of staying downtown, I thought it might be nice to spend my time at one of the resorts in Scottsdale, given it was just a slightly longer drive to the event I was in town for. Thus, I decided to make a reservation at the Andaz Scottsdale Resort and Spa, one of the newest resorts in the area.

Because my stay was midweek and right before the summer low season, I thought I might get a good deal on hotels in Phoenix. That turned out not to be the case, though, since I was booking at the very last minute. Room rates weren’t unreasonably high, but they were certainly not as low as I expected them to be, and they varied wildly from day to day.

I wanted to stay at a relatively new property and earn Hyatt points, so I settled on the Andaz Scottsdale Resort & Spa. I looked at room rates on Tuesday for a stay on Thursday night, and they started at $314 per night with rooms in all categories available. Then, when I checked back a few hours later, the Hyatt site said the hotel was sold out.

Undeterred, I checked again the next morning and found that room rates had dropped significantly. I’m not sure what was going on, but I do know that there was a corporate event taking place at the resort that weekend.

For the night of my stay, room rates ended up being $232 per night in the starter category of an Eames king-bed room. For $10 more, I booked a room in the next category up, a Knoll king room.
