First off let me say that it should read "idea" and that this is a genuine request to try and understand what those of you who use them find so attractive. Please don't enter into the cost aspect, I already understand that. My experience of aires is limited to two, the first one we drove into and straight out again was like a gypsy camp, caravans, vans and washing strung up. The second one was at Calais, very little room between the motorhomes so as a result we were confined to staying inside and then throughout the night we had the constant drumming of ferries arriving and leaving. We like to sit outside of an evening and have a drink, is this possible? I ask this because as I understand it chairs and tables outside are not permitted. Is this a misapprehension ? Would I be right in thinking that trailers aren't welcome as they take up another pitch? Sensible balanced answers please, no high horses.
