Somewhere there was comment about "buying power" Plotter. If the agent has such good buying power I can't see that it a deal that is better than buying direct.
If there is a problem you are still at the mercy of the ferry companies if you have to drive back home, from experience we know through business and pleasure that dealing direct with the ferry companies is normaly better.
As a point of interest my son and some of his Uni friends used a well known booking agents for travel and insurance and break down cover two years ago on a camping expedition.
One of the lads broke his back and they were left stranded by the agents for two days in Italy when one car broke down, the legal eagles are still threatening the company with court action and the other car is still in a French breakdown companies compound. Equipment that had to be left there has gone missing and the agents deny all responsibility despite a recording of the call telling the group to leave the equipment that the agent would have returned with the car!
Both vehicles involved were also given a pricy check over by a well know motoring organisation before they departed on the 8 week trip after they had been serviced and MOT'd as recommened for the breakdown cover.
The faults with the vehile STILL in France should have been picked up on, but they deny any responsility as well.
But then they are linked to the other companies involved!
At one point we had some equipment couriered to the group from Reading to Spain in under 18 hours whilst the professional agents dithered over what they could do when it was partially their fault that a young guys stuff had gone missing! They rang over twenty four hours after it arrived to say they could get it to the next site in 4 days!
Real Peace of mind is a mobile phone with roaming when travelling, as the couple I helped in Italy found last Year when they needed a part for a Fiat powered motor home.
