Q: My wife and I booked a room at the Hilton Chicago three weekends ago, as this is a downtown hotel and a well known brand we knew we were going to have to pay a little more but for that additional price we were expecting to get a quality hotel. We were expecting some minutia of luxury. However, this was not the case with the Hilton Chicago. First, we had reserved a room with a king size bed, but they did not have any available and we were stuck with a queen size bed. Now, we did get a reduced price because of this, but we had made a reservations and expected to be accommodated as we had asked. Second, we had to change our room key twice. The room keys they used supposedly lost their "charge". This is what the front desk told us. So, we had to go up to our room, find out the key didn't work, then come back down stairs get a new key, then get back in. This was highly unprofessional, and they really need to look into their key system. Lastly, we were told at the end of our stay that we had no charges on our room. We knew this was accurate, but I always check just in case. But two weeks later when I checked my credit card an additional two hundred dollars of charges were on my card. I had to call and argue with them for twenty minutes before they took it off my card. Suffice it to say we will not be staying there again.

A:
negative
