The "La Grande Metairie" site in Carnac is a great site and we go there every year. I tried many campsites over the years and this is the best in my opinion. It's a 2-3 hour drive from Roscoff. Sometimes, you can get cheaper accommodation from Kelair/Compotel (Ballinasloe, Galway) by booking an "accommodation only" holiday with them than even by booking at the campsite directly. In the off-peak, season, it's much cheaper. Look at their brochure and compare the prices. Most of their units also have wooden decking and barbecues - enquire. These often cost a lot more with other operators. (I think that they're also the best value for the complete holiday package, if you go that route.) You can book your own ferry. Brittany Ferries have a better ship but are more expensive and sail less frequently than Irish Ferries. I believe that I.F. are upgrading their ship for 2008. Another advantage of Irish Ferries is that you arrive later in the day and have less time to kill - which can be a problem with small children. Also, the sailing home is probably at a better time. In relation to travel/vehicle breakdown insurance, I found Cornmarket to be the cheapest by far. Bonnes Vacances!
