One track in Devon runs endurance events. Teams share a kart over an hour or more, swapping drivers through a pit stop.
The thing that catches groups out. Below the minimum you either pay for absent drivers or book an open session instead.

Sparkford, near Yeovil, Somerset

Christchurch, Dorset
South Coast Karting runs the outdoor Chapel Gate Circuit at Parley, on the edge of Christchurch near Bournemouth Airport. The track is 580 metres long with 14 corners.
Split between four or six drivers, an endurance race often costs less per head than a sprint event, and gives you far more track time.
An hour is enough for a couple of stints each. Two or three hours turns it into a proper day with a real strategic element.
Minimum stop times and mandatory driver changes are what create the strategy. Ask how they run them.
Usually three to six per kart. More drivers means shorter stints, which suits mixed-ability groups.
