I agree with Markol that time share is a lot more annoying than the PR's outside the bars/restaurants and it was the main reason why we stopped going to Tenerife as the harassment got unbearable. We even got to the stage where we were taking the side roads to avoid them but they were riding round on scooters with the tout on the back and there was no escape.
There was a plus side though, if it hadn't been for them then I might not have found the delights of Lanzarote.

I have yet to be approached by time share in Lanzarote.
