Reserve a Room

Go to to reserve a room with EMS. Login with your HLS email account ID (if your email is, your ID is sparker.jd19) and password. Follow instructions for a “Full Service Reservation.”

  • IMPORTANT: the person who reserves space in EMS will be the event contact for all HLS departments (Catering, Media Services, OES, & DOS).
  • For specific questions on the EMS system, please contact the Event Scheduling and Support Office at or 617-495-3129.
  • The system will not let you view rooms unless you enter the requisite minimum number of people (e.g. WCC rooms require a minimum of 4 people).
  • Codes: you will need your org’s primary billing code to reserve a booking and order food through RA. Email Samantha Parker at with any questions.
    • Tub = 265
    • Org = 22130
    • Object = XXXX
    • Fund = 000001 (some orgs have a specific fund #)
    • Activity = 552100 (some orgs have a specific activity #)
    •  Sub = (every org has a unique sub-activity code)
    • Root = 00000
  • IMPORTANT: The publicity blurb you enter when you book a room is what will circulate in Calendar@Law, so please take this part seriously.
  • IMPORTANT: Completing the online request does not guarantee the room is reserved. You will receive a confirmation email from the Event Scheduling and Support Office once the room is officially scheduled.


In your room reservation, you can request Media Services for all AV equipment (i.e. microphone, projector, etc.).

  • A/V requests must be made at least 72 hours in advance.


Rooms might appear unavailable unless you allow for a buffer between the end and start of two consecutive events. For example, if there is a class until 11:50 AM, the system might not let you book until 12:05 PM.

  • Tip: Look at the graphic calendar, then book the largest stretch allowable within that frame.


Ensure the event is not scheduled to begin before/end after the scheduled booking. The room MUST be empty before the next class is scheduled to begin. DOS will revoke event privileges after the first violation.
