A master account is an accumulation of a program’s charges. The group contact should provide clear and detailed information 30 days in advance regarding how the master account should be set up. If the group contact would like a portion or all of the balance direct billed a completed and signed Hilton credit application must be received no later than 30 days prior to the start of the program. The credit application will be processed through Finance. Events Services will advise the group contact if the direct billing request has been approved.
