Renault has already given away all of its 150,000 tickets for this weekend's event and the championship's previous meetings around Europe this season have already broken records. More than 180,000 fans poured into France's Le Mans circuit earlier this season.
The French manufacturer gives away tickets for the series all around Europe for its World Series meetings, which include the 400bhp Formula Renault 3.5 and Megane Trophy cars.
To ensure the quickest time into the circuit for all, the circuit will use the same traffic management plan as it uses for the British Motorcycle Grand Prix.
Donington Park managing director Brian Pallett told Autosport-Atlas that fans should just be patient.
He said: "There could be many fans turning up to a motor racing circuit for the first time this weekend. Our advice is to follow the directions given by the police, and allow extra time for the journey."
The circuit has arranged extra toilet facilities to cope with demand, in what will be the fastest four-wheel action the former European Grand Prix venue will host this season.
Demand for tickets has been so great that many have now appeared on auction website ebay. "These tickets were free," Pallett. "It is a shame that people are now trying to make a quick buck from this."
