For some reason, it is popular for some holidaymakers to exchange names and addresses whilst on holiday.
It is not unknown to return from holiday to find a break-in has taken place.

Another thing to be careful of, is printing your home address on your luggage label so it is visible at the start of your holiday.
We wait until the last day of our holiday to do that.
Forewarned is forearmed.

I'm not suggesting this would happen on holiday in Arillas.
