Click on "Calendar".

Choose the date you wish to book a room. Then choose the time category for the time you wish to use the room. Available rooms in that timeslot will appear. Clear slots mean the room is bookable.

Click in the empty slot to create a booking.

Type in your email address and your phone number. Click "Book".

Some rooms, such as the Squash Court, Terrace Seminar Room, and Underground Lounge, allow more than one person to reserve the same time slot. The booking will have a "How many users?" Please leave that as "1". Each user should make their own reservation separately.

You've now booked the room. When the time comes for you to use it, pick up the keys from the Building Manager's office. After you're done, return them there as well.
