There's lots going on here. So if you're a national trust member then it appears that parking is free and there are different rates for each type of vehicle. But once 6pm happens then "All Vehicles" are £1.00. What about those members with their vehicles, are they still free, after all it does clearly say "all vehicles". In practice the free membership probably holds sway. But while that might not apply to the wheeled vehicles, but does that apply to boat parking.The thing is there's lots of dimensions going on here. Firstly there's members, secondly there is different vehicle types and thirdly different time periods.
