Traveling at 35/36 weeks🚗

Hi guys, I need some help! I'm deciding whether or not to take a 4/5 day mini vacation with my sister, her boyfriend, & my brother to Massachusetts. I live in Pittsburgh so it would be a 9 & a half hour drive there. I will be 36 weeks on friday. Does this sound like a good idea? Anyone have experience with traveling by car in the third trimester? My pregnancy has been smooth with no complications.
