Get an accurate headcount for a group outing
A headcount message fails when it invites a soft 'maybe' and you book on it. Include a firm response deadline, state the cost, and give people an easy way to mention accessibility needs.
What to check before sending
Make sure the draft does not say or suggest that the van is booked, the trip is confirmed, or spots are guaranteed. The cost and deadline should appear exactly as you gave them. Word the accessibility line so people can reply to you privately, not in a group thread. If capacity is limited, the message can say so plainly without adding pressure.
Moving to confirmed booking
Once responses reach your minimum, compile the confirmed list and ask the assistant for a follow-up with payment instructions and trip details. Keep a separate note of anyone who said yes but has not paid, and settle your waitlist policy before the deadline passes.
