An advance reservation for DME is required although a less than astute (sharp; full facultied) room reservationist might forget to make that for you on the spot. When ordering, appealing, reserving, purchasing etc. anything over the phone, write down the name and city of the person you talked to. Also print-screen any relevent information when you make reservations, orders, purchases, etc. on line.
