We were exiled from the Park Hyatt for our first night of reservations due to them overbooking, and were went to the Hyatt Regency. The hotel is an older building that was recently renovated and has a clean, modern feel to it (resembling Aloft by Starwood).
Check-in and check-out were both fast and efficient (it seems like this hotel is designed with the business traveler in mind). We checked in late at night and were happy to find a row of restaurants, patios, and bars right across the street on King - definitely not an issue to locate some late-night grub here.
We got upgraded to the Director's Room on the top 18th floor which had separate rooms for the bed/bath and the living room/work area. There was a nice patio but we were not allowed to use it due to local laws. The view is just OK, there are too many new constructions around and blocks much of the view of anything more interesting downtown.
Overall our experience was simple and comfortable, not a lot of amenities to enjoy here, but I can see this being a great fit for the business traveler.
