Pros
Great employee discount. The discount we received on hotels is by far the best compared to working with other hotel chains. There were also some great people working there, and we had a lot of fun in between taking calls. Quite a few of the supervisors were also very down to earth, and understood that sometimes 'life happens' and you have to deal with it. When management did something to show their appreciation to the employees, it was usually very good. They provided meals during holidays, or offered pizza when they wanted us to work through lunch or take a lunch later.
Cons
In my position, if you were a minute late, corrective action had to be issued. If you were stuck in traffic, were in an automobile accident, sick, etc, and it caused you to be late or call in, corrective action had to be issued. Additionally, in HSC (Hilton Support Center, the name of the help desk for the hotels), we did more hand holding to assist hotel employees than we did actual IT support. Hotels employees would call because they didn't know how to balance a report, check in a guest, or print an invoice. 80% of the calls we took were procedural.
