And it’s a Plan B that avoids the hassle of having to go back the next morning to pick up their car.

Dapto woman Carly Fitzpatrick started Plan B Car Service around a year ago.

Customers can book the service in advance and then drive into town.

When the night’s over, they meet a pair of drivers at their car.

What happens then is one driver gets behind the wheel of the customer’s car and drives it and the customer home.

Another car follows to pick the driver up at the end of the trip.

It means people can sleep off a sore head in the morning without having to worry about picking up their car.

Ms Fitzpatrick said the idea came to her after seeing what her friends had to do one evening.

“I remember once, my girlfriends got a lift in a taxi from town at the end of the night,” Ms Fitzpatrick said.

“Because it was at 2am Wollongong to Unanderra cost them $60, and my girlfriend still had to get back into town the next day because she left her car there.”

Ms Fitzpatrick said the business didn't just cater to partygoers – they can take cars in for services and also pick up people after day surgery and drive them and their car home.
