I had a stay a couple of weeks ago, got a note at checkin welcoming me for my 32nd stay at the property. So must be 32 times I’ve had to ask for an emailed folio rather than hard copy ( and in fairness they always send it). But you might think they’d note it somewhere “ guest prefers folio via email” ( Hyatt seems to have a way to do it efficiently, so why can’t Marriott?)
