This policy is fine with me also. On our last cruise (December '12) RCI had already done away with the Envelops. We always prepay our gratuities so all we received was a letter from the purser stating that this is the new paperless tipping. No vouchers and no envelops. On our last night the staff knew who tipped and they thanked us. I see they modified this paperless policy too. That's fine.
