I stayed at the Hyatt for a conference, which unfortunately coincided with the Coachella Music Festival. Despite the crowds in the area and at the hotel because of the festival, the staff maintained a high level of service and the rooms and amenities were excellent. The rate for the conference packaged in parking and the resort fee so I didn't have to deal with those issues but I would agree that they are annoying. I enjoyed two days at the spa, where I used the steam, jacuzzi, and other facilities for just $20, which was less than I had paid at other resorts. Use of the fitness center is free if you don't use the locker room and other spa facilities. A few of my colleagues had massages (for a separate charge) and they were impressed.
My room was quite large and had a step-down sitting area with couch, chair, coffee table and desk. I was happy that the hotel provided an empty refrigerator in addition to the stocked mini-bar. My only complaint about the room was the noisy A/C. However, since the weather was comfortable at night, I was able to just open the slider and turn off the A/C.
All in all I was quite satisfied.
