The Internet connections are absolutely horrible. In the rooms and the lobby, they have free wireless connections. My room, on the 5th floor, was intermittently up and down. When i asked for assistance, they told me that my room is close enough to the antenna to work. However, they were working on the "configurations" and the system would be up in about 1 week. That's funny, i got the same exact answer during my last visit to the same hotel. Also, why would they have a configuration where some rooms are in range while others are not. They should have antennas throughout.

The conference rooms offer wired connections. However, they're not much better. The entire meeting was affected by dropped and very slow connections - tons of frustration in that room!

In today's world, a business hotel MUST have reliable high speed connections, even if they charge for it.

I travel about 150 nights a year and always stay at Marriott properties. I specifically chose this hotel because the Marriott website listed it as "New Property." Thus I arrived expecting a brand new hotel, and this hotel is certainly not....it's newly a Marriott to be precise.

The staff was very friendly and helpful but I thought the building and rooms were a little on the tired side. The furniture, carpet, curtains, bedding, etc. in my room were dated and certainly not typical of the quality you'd find at most Marriotts. It looked like the property was built in the 80's and has not had a redecorating since then. Everything was certainly clean and serviceable, but the place needed a freshening.

We spent the weekend at this hotel and were pleasantly surprised by the quality of the furnishings and decor. The bathrooms in particular were fairly elegant. The staff was courteous and the weekend rate was quite reasonable for the quality of the hotel.

Oak Brook Hills Resort was a wonderful place to stay while visiting Chicago. Our rooms was comfortable and quiet. Breakfast and dinner in the Windows Restaurant was very enjoyable. Used the Burlington Northern commuter train to get to the City, very easy and convenient! Chicago was a beautiful city to visit!
