Very disappointing!
Our initial room had a super noisy AC unit that clicked and whistled. At first they refused to move us and were pretty rude about it but after continued discussions they eventually moved us to a normal room. 
Next was the worst part, the valet said to pay him for self park and he would put it to our account. I paid him and we parked the car. When we left there was no record of the payment. The Valet Manager and Front Desk mangers both were defensive, combative and offered no refund.
I've stayed at hotels around the world and of course including some Hyatts and I've never run into a problem were the managerial staff was so rude and unwilling to even try and be helpful. On top of that they basically right off the bat accused me of lying about the whole thing. It was nuts!
I was not crazy angry or anything when I approached them, it even took me a second to realize that this was not just a discussion but an actual aggressive confrontation. I was just not expecting that the managers to come off so accusatory and combative.
Terrible customer service by any standard, we won't ever be back which is no loss to us because Indy has many good hotels right downtown.
