Concerts at the O2 and Wembley: we move during the encore, not after it
Twenty thousand people leave an arena in the same ten minutes, and the car parks and approach roads are built to fail at exactly that moment. The trick is simple and nobody does it: we reposition the car during the encore, to a point away from the main exit, so your walk ends at a waiting car while everyone else is still filing out.

What we actually do
The drop, before the crush. Set down at an entrance that works, early enough to walk in rather than push through the gates with everyone else.
The pickup point, agreed first. We fix the collection point before you go in, away from the main doors, so there is no texting in the dark trying to describe where you are.
The encore move. Your driver repositions while the last song is playing, so the car is in place before the lights come up and the exodus starts.
The late finish, covered. Shows overrun and transport thins out afterwards; the car does not leave, so a late encore does not strand you.
How we prepare
Honestly, though
Some arenas, the train wins. The Jubilee line out of the O2 and the trains from Wembley clear fast and cheap. We are worth it for a group, a late finish, or a night you would rather not end on a packed platform.
We cannot beat the car park, only the crowd. If you are parked inside the venue's own car park there is no magic exit; the honest fix is a pickup point outside it, which is exactly what we set up.
Tell us the venue and the night, and we will set the drop, the pickup point and the encore move, with a fixed price back within the hour.
