So being friendly and polite with the front desk staff, bellhops, and housekeeping can increase your chances of getting an upgrade. This is not only for upgrade. This shows you that how your character towards an employee.

Speak to the hotel’s front desk staff and inquire about any upgrades that may be available. Show many things can be done.
