Life is made up of risks. Very real risks such as driving into town on public streets, or less likely risks that still worry some people, such as getting hit by lightning in a blue sky, or a meteorite squashing you. So you have try to judge risks vs. benefits in a rational, not emotional, way.
In general, there are more risks and stresses involved in traveling than staying home. Especially for short periods such as a week or 10 days, corns will do fine without care as long as there is plenty of water and the temps won't be extreme. Longer periods would require a trusted person to stop in, change water, monitor temps, and maybe feed, probably once per week. You may miss your snake, but it won't miss you!
Travel can involve risks such as overheating, accidental escape, crushing accidents, possible car accident, and just general stress (the most likely risk). Of course, some animals, just like some people, are more prone to stress than others.
That is where the risk vs. benefit ratio comes into play. What are the benefits to the travel? Education, sales at expos, showing to friends and family - those are all possible benefits that have to be weighed against the possible risks.
I have traveled to many shows with lots of hatchlings, even taking some on the road for several weeks and feeding and watering while on the road. Although it GENERALLY worked out ok, I did have more feeding refusals and definitely more regurges than with those left at home. Of course, had I been taking well established adults with me, the outcomes might have been far more positive.
So there really is not a cut and dried "one size fits all" answer to the question. Just that, in general, travel increases risks and stress, and that you have to weigh those risks against what you hope to gain in benefits from the travel.
