In my mams case, firstly she did not mind someone "visiting" and parking outside her house, albeit from a different estate, but it got to be regular, two or three days a week, all day and night, it is the boyfriend of the girl in the townhouses, he parked his own car outside my mams, and went to work in a taxi!!!
My mam was getting a wardrobe delivered one day and they had to park off up the road and carry stuff about four houses up. Also, as I said earlier, shopping and stuff has to be carried from three or four houses up.
My sister was getting married in March(and leaving from Mam's) and sure enough leading up to the wedding morning, boy racer was parked outside Mams for the four days solid, day and night leading up to the wedding. We wanted to do photos with the wedding car outside the house and her walking out, etc. One of our neighbours knocked over and requested the car be moved on the morning of the wedding which it was, no problem.
I would go mad if someone went on holiday and parked their car for a week for more outside my house. What if the alarm went off???It would not be an inconveniece to those away on the Costa!
There is a big difference between someone having guests coming for a party overnight and parking outside someones house for two weeks or so, while they enjoy their two weeks away in sunny spain.
