What is the curfew policy regarding travel to from airport

As long as he travels with a copy of his flight plans he will be fine.  Print it out, not on his phone!

Ok! Thanks! I will also be driving past curfew after dropping off my mom! Thanks, Planner!

My local host suggests printing enough copies for everyone in the car (even the driver, if it's a hired car) whether before OR after curfew hours...JIC.

Your driver will appreciate the courtesy as well.

Not a bad idea at all!  Driver absolutely needs a copy.

And welcome to the forums?

Keep copies of Hotel reservations and plane tickets and any other back up materials to prove  your reason for being on the road. You will surely get stopped, but they will let you go promptly with these materials.
  I have a friend that just got in to Cabarete from Punta Cana. He was stopped 5 times, but release immediately with his ticket and home address.

Home address in another country? We are staying at our house driving our car...

Home address meaning where you stay here. Where you are travelling to: resort, apartment etc.
