You say that but in your entire trip I never saw a single Aire or parking spot I Would have stayed at. Not so bad if you arrive late and move early like you seem to do but Im really fussy about where I park up and seldom stop for one night only. Even if you plan its not set in stone. Ill have a rough idea of where I am going and ill have a pre surveyed list of potential stopovers but it often changes. Dont sound like your experience of Aires has been a good one and thats either down to the fact that you took pot luck rather then do research and / or maybe some of the good ones have gone or got taken over. I don't mind paying for decent Aires either but free is always good.
Of course its a bit different for us as we tend to look for places away from the Honey pots usually out in the sticks. I dont need to be in a village or town as we use the bike. You know what they say. Fail to prepare, prepare to fail!!
