Well, since you are supposed to lock down for the last couple of days and then leave the chicks in the incubator for a day, can't you just close up the incubator and leave it?
How much longer are you supposed to be gone after the hatch date? Do you have a friend or relative that could go over and move the chicks to the brooder?
I don't know how much disturbance it would be to the eggs to go on a one hour car journey. I would consider it a risk. Will you even have a brooder available where you are going?
Personally, I would leave the incubator at home and then make the drive home to pick up the hatched chicks if I didn't have anybody to look after them.
Either way, please come back after the hatch, tell us what you decided to do, and how it worked out. This sounds like a good learning situation for all of us.
