Hotel expenses refer to the costs incurred for temporary accommodation during business travel. This includes the room rate, applicable taxes, and sometimes incidental charges like internet, mini-bar (if reimbursed and for business purpose), or room service (if for business meals).
These expenses are typically distinct from a per diem that covers accommodation, as hotel expenses represent the actual cost of lodging.
