My sister does it
When I have to go away for more than a day I have my sister come over to take care of the herps. She comes over the night before and goes through the whole routine with me and I write up detailed sheets about each tank (what, when, and how much to feed, heat ranges, humidity ranges, what to do to lower or heighten heat and humidity, etc.). She usually doesn't have any problems but if she does she can always call me. I don't have a large collection yet but I'm getting snakes in a few weeks and she doesn't relish the idea of feeding mice so I may have to find someone else for that. I pay her 10$ per day and she seems pretty happy with that.
