Online booking for meeting rooms
Offer clear booking options for members and visitors. Set appointment times and payment requirements for each service.
One event type per room for visitors, paid online, plus an invite-only free event type per room for members, with start times every thirty minutes.
Members and visitors want opposite things#
A member booking a room for twenty minutes should not see a price or a card form. A visitor should not be able to book a room for nothing. A shared spreadsheet gives you neither, and two booking systems give you double bookings.

Suggested booking questions: How many people? · Do you need a screen or a whiteboard?
Give members an invite-only event type so they book without seeing the visitor price, and keep a public paid event type for everyone else. Same room, two doors.
Same room, two doors#
For each room, a public paid event type for visitors and an invite-only free one for members. Both are the same room, so a booking through either blocks the other — which is exactly what you want.
Start times every thirty minutes#
A one-hour duration with Show start times every set to thirty lets a booking start at 10:30 without wasting the half hour before it.
Book from the corridor#
One hour’s minimum notice, so somebody can book the room they are standing outside.

Common questions
Can members book free while visitors pay?
Yes. Make two event types for the same room — a public paid one and an invite-only free one — and give members the invite link. A booking through either blocks the room for both.
How do I stop two people booking the same room?
Each room is one event type, and a confirmed booking removes that time from every offer. A slot being filled in is held until the person finishes or gives up.
Can bookings start on the half hour?
Yes — set Show start times every to thirty minutes while keeping a one-hour duration.
