Dover to Calais and back again!!

I am due to cross over to France on the 15th August with my wife and two kids sailing from Dover to Calais with DFDS, and then return in the opposite direction on the 29th August and i just wanted to ask if anyone has experienced problems with the illegal
immigrants seeking passage back to the UK, and whether this is confined to just Calais, or whether Dunkirk is subject to the same problems?

thanks
