The Robins' board of directors have announced they will pay for as many coaches as the supporters can fill for the trip to St James Park.
Mark Yates' men are guaranteed an League Two play-off place, but automatic promotion remains a possibility and the manager believes the extra backing in Devon can help make the difference.
"It would be great to see as many Cheltenham supporters down there as possible," he told the club's official website.
"The support on Saturday was really good and if we can replicate that at the weekend at St James Park then I know the players will respond.
"I'm delighted the chairman came to this decision and it shows how much we want to win this game."
