How many shuttle buses does your event need?

Four numbers decide the answer

Planners often start from the guest list. A 400-person event does not need enough seats for 400 at once. It needs enough runs in the busiest hour. Four numbers settle that.

• Peak people per hour: how many need to move in the busiest 60 minutes, such as the hour before the first keynote.
• People per run: seats on the vehicle, multiplied by a fill target.
• Cycle time: minutes for one full loop, from leaving the hotel to being ready to load again.
• The longest wait you will accept: it caps the gap between buses.

Then divide. Buses needed equals peak people per hour, divided by (runs per bus per hour times people per run), rounded up. Runs per bus per hour is 60 divided by the cycle time.

Cycle time is the number only you can supply

We do not print a journey time here. It changes with the route, the hour and the venue’s drop-off arrangements, and a figure copied from a map misleads. Build the cycle yourself: drive out, unload, drive back, load, plus a buffer.

Time a trial run at the hour you will travel. Allow extra on the first morning, when every driver in the city is learning the route, and tighten the plan once you have seen the real timings. Our event transport page says the same for the first day at a new venue.

People per run: seats and a fill target

Take the seats from the vehicle, not from the brochure. A 50-seater coach has 50. A 30-seater mini coach has 22 to 30, depending on the vehicle assigned, so plan on 22. A Mercedes Sprinter has 16 and a 13-seater van has 13.

Do not plan on 100 per cent. Late registrations, a VIP who joins and the last three people at a hotel all need a seat. We use a 90 per cent fill target here: 45 on a coach, 20 on the mini coach. That is a planning habit, not a rule. Raise it if your guest list is closed.

A worked example: 400 delegates to one venue

Assume 400 delegates in hotels clustered close together, and one venue. Assume 75 per cent arrive within 90 minutes of the keynote. That is 300 people in 1.5 hours, or 200 an hour. The table shows how the answer moves with the cycle time you measure.

Read one row. At a 30-minute cycle a coach makes two runs an hour and moves 90 people. Two hundred an hour divided by 90 is 2.2, so you round up to three coaches. Cycle time divided by coaches gives the gap between them: ten minutes. The same job on mini coaches takes five. The bigger vehicle wins the loop because every run carries more, but only if the hotels can take it. Our guide to the four vehicle sizes shows where a coach does not fit.

Check the gap between buses

The sum can come out right and still feel wrong in the lobby. People wait, on average, half the gap. With three coaches on a 30-minute cycle the gap is 10 minutes. If your group will not stand for more than five, add vehicles until the gap shrinks, or run one hotel on its own loop.

A trial morning is worth the effort. Count how many people reach the kerb in each 10-minute block, not just the total. Real arrivals bunch around the start of sessions.

The evening return is a different sum

Arrivals spread out. Departures do not, because a final session ends and everyone leaves at once. So set the longest time you will let the queue take to clear. For 300 people with a coach cycle of 30 minutes, clearing in 60 minutes means 300 an hour, which needs 300 divided by 90, so four coaches. Clearing in 30 minutes means 600 an hour and seven coaches.

The fleet is set by that choice, not by the morning. Two ways to lower it: stagger the end of the last sessions, or agree a fixed departure time for each vehicle so people can choose their bus. Plan one last run for the delegates who stay on to network.

Add a spare, then get the count in writing

Many planners add one stand-by vehicle to the calculated number. Ask for it as a line on the quote, not as a promise in an email. A good quote lists the vehicles for each day and each hour, which is why we point planners to the guide to bus quotes.

For larger events a coordinator stays on the ground, calls the loads and watches the gap. Read how a private loop works on our shuttle service page, and how the airport side is planned on the airport transfer page. Send us the venue, the hotels, the peak hour and your cycle time, and we reply with a fixed written quote.
