I know you said you don't want to bother the person checking on the house, but it'll most likely be a mild inconvenience. I'd suspect you know your humidors. If you put fresh bovidas in (over-sized) when you leave, how long do you expect they'd last? Have some spare bovidas at-the-ready and ask them to swap, when the time is near. You want to open the plastic containers weekly. That would be far more of an inconvenience. Or were you taking plastic with you, to have some stogies?
