I choose my hotels starting with the car park.
Me too. Recently en route to Fort William we stayed overnight at The King's Head, Richmond. I phoned ahead to see if I could reserve a space in their small and awkward car park as I didn't want to leave it in the town square on a Friday night. God bless Louise, the manager, who said when you turn up let me know and I'll get you parked. Sure enough she came out straight away and started moving wheelie bins (impressively, two at a time!) to give me space to park safely.
At service areas, best to avoid parking next to White Van Man. Big doors. On this same trip to Scotland I watched as the driver's mate got in, with hands occupied by coffee and burgers - and clouted the car parked next to him.
