I wish I had this problem.
I always check out personally to request a printed folio. I do not want folios emailed to me. I ask the front desk not to email me my folio. Yet I always get a folio by email. Worse, I usually get two.
I have no idea what IT programmer thinks it's a good idea to email preliminary folios at 0100 on the day of check out. Don't these people realize that late additions to the bill are pretty common at full-service hotels?
