CC route planner

I am booked in at The Howard, Rosedale Abbey Club Site - the site instructions say that the A170 Sutton Bank does not allow caravans so I decided to use the Club route planning service. I found it frustrating to use - when I entered the site name as the destination it sent me to Kings Lynne - not Yorkshire. Eventually after several attempts I got the directions I wanted but they are not very good - how does "bear right into road" sound to you?

The last statements say that the route has been created by the Caravan Club and is powered by Microsoft - there then follows a discalimer "routes provided may include roads unsuitable for vehicles towing trailers or caravans" Can anyone tell me what is the point of the Club producing a route that may not be suitable?
