Hawarden is quieter than Liverpool, though still offering a full ATC service and a wide variety of traffic. I use Flintshire FS for my revalidations and the staff there are always very helpful. I did my initial training at Speke (now Liverpool) in 1958 so I cannot now vouch for the schools at Liverpool, but I do see their training flights doing touch and goes quite frequently at Hawarden.
