One track in Guernsey runs team building events. The appeal is that karting is a genuine leveller: seniority stops mattering the moment the lights go out.
Drivers share a kart and swap over across an hour or more. Far better for building a team than everyone racing individually, and often cheaper per head because it is priced per kart.
Most operators take card on the day. Fewer will invoice a company on thirty days, and it is worth asking before you commit.
Meeting or dining space on site turns half a day into a full one and saves moving everybody twice.
Height, weight or medical limits will rule someone out. Sites with a simulator or a second activity handle that gracefully.
