Making Your Corporate Event Ideas for Large Groups Work

Planning Timeline:

• 8-12 weeks before: Book venue and key suppliers

• 6-8 weeks before: Send save-the-dates and gather dietary requirements

• 4-6 weeks before: Finalise activities and send detailed invitations

• 2-4 weeks before: Confirm numbers and brief all suppliers

• Week of: Final preparations and contingency planning

Budget Considerations: Consider cost per person rather than total budget. Activities like inflatable challenges often cost less per head than fancy dinners. Factor in travel expenses if people need to reach external venues.

Accessibility Matters: Always check accessibility requirements early. Choose inclusive activities where everyone can participate meaningfully. Have quiet spaces available for those who need breaks.
