From the moment I stepped into the hotel I felt like I was walking into my own castle and everyone was there to serve me. Checking in was done in a matter of seconds and the receptionists were very friendly. I only had one bag with me but they still insisted on helping me carry it to my room, which I loved since I had just had quite a long flight, and made sure I had everything I needed before wishing me a happy stay in the Hyatt Regency Chicago. After settling in and resting for a while I called room service and ordered some dinner which was provided very quickly and tasted like something out of a 5 star restaurant. Overall my experience was very positive and I would be glad to return to the Hyatt upon my next visit.

Ex Output:
positive

Great front desk staff, the rest of the experience was dreadful. The room service staff have to be among the most poorly trained I have ever encountered. We had to ask FOUR times for the staff not to slam the supply closet, adjacent to our room (almost in the room itself). They do these random room checks for the minibar, as if the entire budget hinged on the sale of a can of $9 peanuts. The roomservice is also equipped with walkie-talkies as loud as megaphones. If you like sleeping in on your vacation, don't stay here. Also, the hotel was under massive construction, a detail that was conveniently excluded from the website. SO we had to take the elevator with construction workers just about every time we used it. No discount because of the work and noise. I'd rather sleep in a box in the alley.

Visiting during a busy 2day conference in Chicago. Most hotels booked solid. The full hotel allows you to meet a wide array of customers. Everyone is complaining about service, cleanliness, and overall experience. Location is good. Hotel is tired. Employees surly. Too many cool properties to choose from in this town, will never stay here again and will re-think Hilton in general

negative
