It is NEVER recommended that you surrender your passport when hiring a vehicle or similar situation. If a service provider such as a motor scooter rental business is unwilling to accept a photocopy of your passport, move on and try someone else. Every hotel will photocopy your passport at check-in and make a note of your visa (or visa exemption) details. Remember that your single most important document that you have while overseas is your PASSPORT -- guard it well.
