Arrival & Departure
The scheduled time allotment for all-inclusive package events varies, and typically runs either 2 ½ or 3 ½ hours. Refer to individual all-inclusive package details on the pricing section of our website. Other events are scheduled for 3 ½ hours for a corporate or personal event without an exclusive; with an exclusive for 5 hours and for a retreat eight hours. If the event runs past this allotted time – and you are welcome to stay as long as you want, there is an overtime charge per hour or portion thereof. If you go into overtime drinks will be served on a cash bar basis (guests pay) or a consumption basis (you pay). Your guests will be allowed to tour The Mansion (and go shopping) for the first 45 minutes of our event, at no additional cost. Room assignments and table set-up arrangements and preferences will be taken into consideration, but no guaranteed, as this will depend on your final head count. As this is a historical and residential neighborhood, D.C. law prohibits guests to give you a “send-off” in the front or back of the Mansion, or use our large garden and pool area before, during, or after your event. If you or any of your guests violate our arrival and departure requirements, you will be charged a $750 penalty, per occurrence. These rules are critical for us to maintain our license.

You can use your own computer. the fee structure for AV equipment is provided in the pricing section on our website.
you are required to test your presentation 24 hours in advance, as each computer is programmed differently. Failure to do so will result in a $100 surcharge. In addition, the mansion will not be held responsible for technology glitches if you do not do this.
