For the price charged per room this hotel leaves quite a bit to be desired. I will say that the staff was incredibly helpful and friendly even with all of the snafu's. It started with our adjoining rooms not being ready upon arrival (even though it was after the allotted check-in time). A drink credit to the bar was provided for us to use during the wait. 2 hours later we were still waiting. Finally, our rooms are ready and the bellhop takes us and our luggage up only to discover the rooms are not adjoining and no where near one another. So back downstairs to the desk we go where it takes another 1 1/2 to find adjoining, clean rooms.
The first thing I notice are the stains on the carpeting, grubby fingerprints on the doors and corners of the wall just like i find in my child's room- a general worn edge if that makes any sense. The bathroom was tiny with mold in the grout in spots and had a separate dressing area which was quite ample and well lit. As far as noise, we were around the corner from the elevator so there was foot traffic but luckily no one was too rowdy.
Overall, I would say the location is good if you need to be downtown. It was a "nice" hotel but definitely needs some love if the price is to remain that high.

Individually, many of my complaints might be petty.  But collectively, they suggest that management is asleep, and needs to actually take an interest in what's going on around the hotel. 

(1) The elevator certificates displayed in the Radius Tower elevators expired in April 2012.  I'm going to assume that the elevators actually have been inspected and it's just the certificates that are out of date. But how many employees must ride these elevators every day, and have seen, said, or done nothing?  What does that say about the corporate culture of the hotel?

(2) I actually read the policies on the back of the door.  Its says no outside food/drink is allowed.  Presumably it isn't actually enforced, but this sounds like a rule I'd expect to see in a third-world hotel, not a Hyatt.  I'm an adult and don't appreciate rules that seem to think I'm a child who can't be trusted not to leave a trail of crumbs.

(3) The design of the rooms in the Radius Tower is trendy but not entirely functional.  But the real problem is the lights.  Twice, the light behind the bed and the hall light turned themselves on in the middle of the night.  I ended up removing the bulb from one of them.  And yet the floor lamp had a loose switch and was a struggle to turn on at all.  I don't like to think that a skyscraper hotel has questionable wiring.

(4) There is no automatic checkout.  One has to leave a voice mail, or visit a website, or go to the front desk.  I can't remember the last time I stayed at a hotel that didn't just slip a statement under the door early on the day of departure.  Time to join the 21st century, Hyatt - I want to just leave when I'm ready, and not jump through hoops for your amusement.

(5) One day, my room simply  wasn't cleaned.  Again, I can't remember that ever happening before even at a low-tier hotel.  (What does a Hyatt Regency purport to be?)

(6)  And I could go on.  Paper cups in the room instead of glass - how chintzy.  Mysterious loud and repeated noises from the service corridor during the conference - perhaps work should be done at other times? Etc.

Is it a bad hotel?  No.  But until it ups it's game, it doesn't deserve my - or your - patronage.

The hotel is nice, and the rooms are nice. My issue is that one night, at 3am until 5am I had a stranger banging on my doors and jiggling the knobs aggressively in an attempt to get into my room. I have a video that I took in my room to record how loud this was. I called security after the second incidence and they said they would check it out and nothing was done. They did not even check in on me. And so it continued until 5am. As a single woman traveling alone, I find it quite concerning that nothing was done or that nobody at the front desk would followup with my complaints. I did make sure the deadbolt was on. Otherwise, the hotel is nice, but just be careful when it gets busy. It was a busy weekend and perhaps that's why they didn't care.

You could be staying here for numerous events like new years eve, conferences/conventions, reunions, wedding/receptions there are so many things that take place here which is why most people stay here. Its a huge hotel, built well & deigned efficiently. Greatest thing about hotel is its huge open air interior corridor. Everything else involving room is just an average good room, solid. Never had any issues in my numerous stays at this hotel -only reason i would stay here is because my event is inside of this hotel -it wasnt because room is very impressive, although probably one of the best balcony type rooms in this city. Glass elevator is fun for all ages, yea i said it -All ages. The location is perfect as far as hotels in downtown go -you can exit the hotel in any direction & there of plenty of restaurants & shopping in area. Dining inside the hotel is surprisingly good from my one time eating there. If your thinking about hotels in downtown & the tall Westin is in contention, stay here. 3.5 stars.
