You sure can. Just a heads up that for hotels, car rentals, and gas stations, merchants may put a pre-authorization hold (usually around 15-20%) on your card. This is by no means a charge, however, your funds will be held to the ensure you have enough to cover the purchase (plus incidentals where applicable). The correct amount will ‘settle’ within 15 business days after you check out. 

Life Hack: to get around this nuisance, book your hotel using a different credit card and then pay the final amount using your KOHO card.
