If you plan to work for a hotel chain, I can recommend the Westin. There are properties that are not corporate controlled, those would be franchised, and might have a different environment as compared to corporate hotels.
Westin cares about its people and its guests and strives to have high standards. If you are truly a people person and care about giving the best, look to the Westin.
A people oriented company
Franchised or name leased properties might not have the same standards.
