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 ensure you have enough to cover the purchase (plus incidentals where applicable). We can't release these holds ourselves.
The correct amount will ‘settle’ within 16 days after you check out. Our support team is unable to expedite the release of this hold.
Life Hack: to get around this nuisance, we recommend booking your hotel using a different credit card and then paying the final amount using your KOHO card.
