The term 'PARKING OPTION' can be broken down into two crossword solutions: VALET (5 letters) and HEADIN (6 letters). VALET is a service where a driver leaves their car with an attendant, who then parks the car for them. This service is often used in busy areas such as airports or hotels. HEADIN is a type of parking where the driver pulls into a parking space head first, rather than backing in. This type of parking is often used in tight spaces or when the driver needs to quickly exit the parking spot.
