If it's only 6 days, then you should have nothing to worry about. Getting packed up and taken on a 9 hour journey will be stressful for the scorpion.
Make sure the substrate is nice and damp, top up its water bowl and feed it before you go. Remember to remove any uneaten insects before you depart.
I went on a 3 week trip to the US last year, and didn't get anyone to care for my scorpions. I keep mostly desert and temperate species, so I cooled them down and put them into 'hibernation'. A little earlier than normal, but it was November anyway, so it was no real bother for them. For the few tropical, humid climate species I have, I just made sure their enclosures wouldn't dry out while I was away. No problem for a scorpion to fast for 3 weeks, even the juveniles.
