  • We strive to respond to all internal requests within 3 to 5 business days. More time is sometimes necessary to process large and/or complex requests.
  • We are making every effort to get to each request as quickly as possible, however, requests made less than 5 business days prior to the requested event date may not receive a response from our office.
  • Once a scheduler has processed your request, he/she will confirm the event via e-mail.
  • If the space or time you’ve requested is not available, a scheduler will contact you to discuss alternatives. It is recommended that you include alternative space and times in case your first choice is not available.
  • DO NOT proceed with the planning or advertising for your event until you receive written notification that a space has been assigned to you.
  • If you are partnering with an external organization, your event qualifies for the Sponsored Rate. Please fill out the Sponsorship Request Form  and return it to Lesley Irminger.
  • Inclement weather policy
