First of all, let the regional cordonator know, they might be able to provide some VIP access for them.
Second, plan out the time there. Have them coming in for a match or two, get some kids to explain the game and their team, then move them through the pits (remember to bring safety glasses for them!), show them your robot (get students to explain!), and then show them anything else you find interesting (inspection row for example if it's on thursday).
Overall, give a structured professional presentation and you'll do great. Most of the time businesses will just be amazed even if you did it in your boxers and spoke in Klingon.
