Actually coptcha, the owners of vacation homes are rarely in them...You can work this out quite easily, since they are being rented out for the majority of the year to strangers. Strangers, who will think the package belongs to the owner and thus leave it untouched, probably bringing it into the house warm and safe for which you have the key. And like I said, the key is almost always about the front or back door area. People are fundamentally lazy. You should watch out for CCTV though, that could cook your goose ASAP.And, should you be 'caught', well, you could easily be a 'cleaner' or 'inspector'. You just need one or two props. And if it's the owner, aha, you got the wrong house today. This is totally feasible, because these houses need to be cleaned between every visit by holidaymakers and are inspected frequently by people who visit thousands of these houses.As long as you're not stupid enough to start removing items from the house or start living there or something, it's nearly impossible to get a B&E rap. It's not as hard as it sounds, it's literally a 2 minute operation every couple of days for which a timetable is handily posted onto a website.
