Planning a spring carnival in Marin or San Francisco runs on a tight calendar. Schools compete for limited field space, vendor availability, and early-season weekends. A clear reservation timeline keeps the event smooth, safe, and fully stocked with the attractions students expect.
Choose your date, confirm campus space, and reserve major attractions first. Large obstacle courses, premium combos, and interactive games book out early in both counties. This is also the time to request insurance documents and begin a rough layout.
Build out the rest of the lineup: smaller inflatables, sports games, toddler pieces, concessions, generators, and tables. Share a draft site map with your rental provider so they can flag spacing, power, and access constraints.
Lock in delivery times, volunteer assignments, and final inventory. Schools in Marin often adjust for uneven fields, while San Francisco schools confirm gym height or blacktop space as backup for fog or rain. Final details now prevent last-minute substitutions later.
Walk the site, measure gates, confirm access paths, and check ground conditions. Verify your weather plan and reconfirm the vendor’s arrival window to avoid conflict with drop-off traffic or limited parking.
Mark setup areas, assign a point of contact, and prepare volunteers for safety monitoring. Ensure circuits or extension-cord runs are clear if any units move indoors.
Obstacle courses: 90–120 days
Premium interactives: 60–90 days
Standard inflatables and games: 30–60 days
Once your spring carnival date is approved, reserve inflatables and games as early as possible—ideally 60–120 days out. Early booking secures better equipment, smoother logistics, and fewer surprises for PTA teams, administrators, and volunteers.
