There won't be a lot of time to relax or honeymoon however as Hartley is needed back in Europe to prepare for the season ahead before the end of January.
"We have a few days after to enjoy with friends and some time to get on my mountain bike a bit," he said.
Hartley will help work on the development of the Honda power train that Toro Rosso will employ in 2018. He will get his first chance to drive a Honda-powered car in winter testing at the end of February before the first round of the championship in Melbourne in March.
