Handling Staggered Arrivals Without Repeating the Main Briefing
This is an invented planning exercise, not a real customer event.
Background and constraints
A fictional evening social expects 24 people arriving in two waves because of work schedules. The host wants late arrivals included without restarting a group puzzle halfway through.
Exact inputs
Start: 18:00. Available duration: 120 minutes.
Drop-in welcome and optional drawing | 30 Shared main briefing | 10 Collaborative map challenge | 40 Refreshments and viewing | 25 Closing | 15
Actual calculated running order
| Activity | Start | End | Minutes |
|---|---|---|---|
| Drop-in welcome and optional drawing | 18:00 | 18:30 | 30 |

| Collaborative map challenge | 18:40 | 19:20 | 40 |
| Refreshments and viewing | 19:20 | 19:45 | 25 |
| Closing | 19:45 | 20:00 | 15 |
Total: 120 minutes. Remaining: 0 minutes. The entered schedule fits within the available duration.
Planning process
The host protects the first 30 minutes as a low-dependency arrival activity. Essential puzzle instructions start at 18:30, after the second wave is expected. A printed one-page briefing remains at the welcome desk for anyone who arrives later still.
Result explanation
The main challenge begins at 18:40 and ends at 19:20. Guests who arrive early have something meaningful to do, while later guests do not miss an irreplaceable role assignment. The plan fits exactly within the two-hour booking.
Alternative
If arrivals cannot be predicted, choose independent stations with repeated briefings rather than a single dependency-heavy challenge.
Execution notes
Communicate the shared briefing time on the invitation. A welcome activity is optional participation, not a penalty for arriving at a different time.

FAQ
Does this check my venue calendar?
No. It compares entered segment durations with the entered limit; it does not access external bookings.
What happens when a segment changes?
After the first calculation, edits to the inputs recalculate later times. Review any conflict warning and save the revised plan.
