A proof-of-stay is required for all lodging expenses charged to sponsored awards. When lodging is paid through an online service like Expedia or Priceline, it may be difficult to obtain a bill at checkout. The lodging was not paid directly to the hotel, and, therefore, they generally are not able to provide a receipt at checkout. However, the hotel should be able to provide you with some sort of proof-of-stay. The traveler should request something from the hotel to indicate they stayed there. Examples include a zero-balance folio for the room indicating the traveler’s name on the room or even a note on hotel paper with the dates of stay and the traveler’s name, signed by the hotel.
