Just Okay; Nothing Special
Huge lobby with no real retail. Luckily there is a good mall very adjacent. But don't count on this lobby for anything other than a Subway sandwich, a really bad pizza or Starbucks (mornings only for the Starbucks). Has a 'ghost town' like feel to it, which I really don't like it a hotel. 
Location is close to EVERYTHING. That's the biggest plus of this hotel.
Rooms are comfortable, clean and have a lot of outlets for a Hyatt. Wireless is $9.95 for 24 hours. I bring my own. Paying hotels for it just makes no sense with the prices you are charged for your room.
Fast room service, decent food, reasonably priced. 21% gratuity is included on your bill, so don't tip unless you think the service was fantastic.
Valet parking is $30. The self park is $22 for the day so you don't really save that much. There are less expensive options - the lowest is about $20 a night, self parking, at the Circle Centre.
Flat screen television (not high def), okay channel selection, refrigerator included in room, no tub-just a shower. Bathroom has decent lighting. Tiny work desk. If you plan on doing a lot of work in your room, you might not like it. Very limited surface space.
All in all, a decent place. But nothing special. If you're looking for 'special', I'd head to the JW Marriott down the street. Much nicer place.
