Nothing to do with LoCosts but I often have to go out on business with colleagues and we normally try to meet up somewhere so we share a car for the
majority of the journey.
Trouble is where to leave a car all day safely.
Motorway service areas are an obvious choice but they tend to restrict parking to 2-hours and I'm always a bit concerned about getting back to a
big parking charge (or a clamp).
I wondered if it would be possible to use members local knowledge to somehow set up a database of recommended places.
It's probably impractical but I'd certainly find it very useful.
we used to met up at out of town car parks and supermarkets, the out of town ones dont have limited parking like the intown super stores
National Car Parks? Or are they too expensive?
As stated - try the Park and Ride car parks - they are often ludicrously cheap
OR - if you're really cheeky (like me) I would use TRAVELODGE / LITTLE CHEF car parks - constant stream of people and no clampers

John,
I often have to do the same thing - like suggestions above we look for out of town superstores. Never had any problems so far.
Supermarkets are best. I know of a few people that do it.
