β€œWe had such a beautiful time at the Marriott Marquis. It was our first time in Chicago and for our anniversary. The front desk, (I think her name was Lisa) was top tier. As soon as we checked in she welcomed us to Chicago and said Happy Anniversary. She was also able to add an extra night at the same price in the same room. We got a complimentary upgrade with champange/ chocolate covered strawberries. The room/ view was gorgeous during the day and night. T…”

β€œThe rooms were nice and comfortable with the amenities we needed for the week. The hotel was in a good location for us by the Mccormick Convention center. It is a bit away from all the city attractions, but nothing a short walk or bus ride can't fix. It is a 5 minute walk to the green line and easy access from there to the airport. I would recommend πŸ‘Œβ€

The hotel is conveniently connected to the convention center, though it’s about a 20–30 minute walk, so something to keep in mind if you’re attending events. The room itself was spacious and comfortable, and most amenities were well provided. The only downside w…”

β€œI’m not one to go and publically make remarks about my distaste for a company. However, this hotel and its staff have been incredibly frustrating. I’m Marriot Platinum, and after the last few Marriott’s I’ve been at, I don’t think I will be anymore. Wednesday night late we check in, and it’s one guy at the counter helping a ton of people. Which I understand can be overwhelming. We get to the counter and I ask about parking. He says the following: -$60 a …”
