Usually VFR in the rotary, and the routine is hold at the North Terminal, and then land after whichever sky darkening piece of alloy has just touched down. Sadly they then make us follow A lumbering line of jumbos to a hold for a runway departure. They just can't get the idea that all I need is somewhere reasonably flat and a route nothbound away from the approach/departure path, which is pretty much what Heathrow provides.
Verticalhold,
Years ago, there was an 'H' at Gatwick positioned on what is now taxiway Lima, just North of stand 150, if you have a plate of Gatwick to hand. This was fine when this taxiway was a cul-de-sac but it had to be removed temporarily for WIP. When we wanted to replace it with something more user-friendly we did risk assessments on all the possible locations and came up with...nowhere! Thus, all rotary traffic now has to land/take off on the runway in use and thus has to book slots instead of just dropping in. Something of an own goal, really. Vallance Byways now does good business in rotary movements and good luck to him.
