While working in Belgium a few years back I did this for months on end, every second weekend, saved a fortune. I was using a different rental car every time though BUT my colleague (who put me on to this plan) did it for a whole year pretty much every weekend with his UK registered car. Never once did 'the computer' flag this up.OK, I misunderstood.
I guess it depends upon how long it takes before Eurotunnel's IT system gets coded to check for unused return tickets then
