Have never been camping before but have been looking at parks in Italy and Spain and looking at Trip Advisor etc. I am quickly learning that parks/campsites - am thinking of those with chalets/mobile homes - have a number of different firms using them, like Eurocamp, Canvas, Bolero, Thomson AlFresco and Ellevacanze.You can also book direct with the park. Is there any quick way of finding out which firm using a particular park is cheapest or do I have to go through each operators online brochure? Any tips on which firms to avoid? Also, some firms charge extra for 'linen packs' whilst others include this in the price. Any feedback appreciated.
