Regardless of the length of the trip you want to cease all feeding at least 5 to 7 days before the day you leave and give the animal time to fully digest his meal.
If a regurgitation happen you want to clean up right away not when you come back, not only because you do not want to leave something decompose in your house but also because at time a regurgitation is also accompanied with a large amount of stomach acid being thrown up and the last thing you would want is to have you snake sit in this for an extended amount of time.
Sure in most cases nothing happens but you should always proceed as if something would.
