Never Again
I have never felt the need to write a review on hotel until after my experience at the Westin on Michigan Ave. If I could give this hotel zero stars I would. 
So here goes, we checked into the Westin on Saturday with my family for the Festival of Lights show, a tradition for our family the past few years. Upon arriving to the hotel we were told that our room would not be available until after 4 pm (check in is at 3 pm or earlier if your room is available) because the current occupants had paid for a late check out. My immediate response was to ask why they would allow late check out on a day when millions (yes millions) of Chicagoans come into the city of for the lights show. Not only was the staff extremely rude and could care less that we were upset, but If you read other peoples reviews you will see that they had similar or worse experieces with their staff than us. We were told that they paid for a late check out so it was out of their hands. So its obvious they care more about money than service at this hotel. I asked to speak to a manager and was told that he was busy - you dont tell a guest that the manager is too busy to speak with you, you get on the phone and call them to come meet the guest!!!
To make matters worse we were then told that the room that we booked (a Michigan Ave facing room) was not available because they were sold out. Mind you we made the reservations two months in advance specifically requesting a Michigan Ave facing room. Basically, I was given the impression that another group paid more for the room and so they had to give it them. We were obviously unhappy at this point and were hoping that once we checked into the room that everything would be perfect, boy was I wrong. When we walked into the room the carpet on the floor was torn and you could literally pull it off the ground exposing nails, tacks, dust and dirt. I took pictures to prove it, I have posted here so you can see for yourself. The room was dirty and extremely dated, not something I expected from a hotel on prime real estate right on the Magnificent mile. I complained to the manager upon check out and he actually took the room off the market because it was not safe!!! So why would you allow people traveling with small children occupy that room in the first place!!!! I was disgusted and really just wanted to go home. We would have left and gone to another hotel but due to the festival all the rooms in the surrounding area were booked. 
To add the cherry on top due to the lack of security on a day were occupancy was close to100% an unfortunate incident which was all over the news that day, my nephews along with every other child staying at the hotel that night was absolutely traumatized. To make matters worse the hotel staff and management acted like nothing happened and did not make mention of this incident to anyone staying at their hotel that night. Im not even sure if that legal or not, if someones safety is compromised they have a right to know. At this point I was furious and told the manager that they should have paid us to stay at this hotel. I wasn't expecting 5 star treatment, but to be honest our experience with the Westin, their rude staff and disgusting hotel rooms almost ruined out entire weekend.
I am still so mad about this that I will go out of my way to make sure that everyone on facebook, twitter and other sites you can review hotels on knows about our horrible experience at this hotel. Maybe then they will cough up the dough to train their staff better, renovate the rooms and make them safe for people traveling with small children. When you pay a premium price I expect premium service. Their acclaimed service quote "We provide unparalleled service for business and leisure travelers with elegant function space for all types of events" is clearly false advertisement!!! Do yourself a favor and stay somewhere else.
