The shuttle bus to ORD does not pick up the passengers correctly, and the information is not shared between the hotel and the service company.
The front desk staff at the hotel is not always the same.
Some are polite and some are clumsy.
The reason why some are polite and others are clumsy is because they are not thoroughly trained.
For example, on the first and second days, the front desk staff gave us two complimentary bottles of water each, but on the third day, the staff member in charge of the third day almost ignored us and did not respond to our requests, as if he was trying to get us to pay for it. I would have preferred to keep his name, but he was not the right person for a hotel person.
