We've only had a hamster for a couple of months so it's all a little new to me. We are going away boxing day afternoon, then returning home the afternoon of the 28th. So 1 whole day away + 2 nights.
He doesn't chew on the cage and doesn't want to come out every day atm now it's cold. If we did leave him at home of course we'd clean the cage before we went, change toys around, put food out, hide food, give him plenty to rebuild his nest with. Depending on the forecast we'll set the heating on to a reasonable level, we have a cat who is happy to be left (yes I'll male sure she can't get into the room). Then leave a small oil filled radiator in his room and set the level on that.
We could take him with us but I think a couple of hours in the car there, then back, would be more stressful. He's in my sons room and it's pretty peaceful in there most of the time. Or there is someone a short drive away we could leave him with. They're not pet owners but would keep an eye out.
