Anyone looking to purchase breakfast or dinner on-site can do so with a credit card at the door of the dining commons.

Please note that additional meal purchases are non-refundable.

Additional Guests

Additional tickets for accompanying persons may be purchased at a cost of $250 per guest. This covers the Crypto 2023 evening receptions only (Welcome Reception, Monday Banquet, Tuesday Rump Session, and Wednesday Beach BBQ).

Parents with children under 12 do not need to register the child as an accompanying person. Please email the general chair to advise them of this as well as discuss any additional needs you may have around travelling to the event with children.

Meals for the De La Guerra Dining Commons lunch times can be purchased for additional guests onsite with credit card at the dining hall, if desired. As stated above, these are non-refundable.

Special Diets

Campus Catering, with advance notice, may be able to accommodate restricted diets at catered events. Menus may be adjusted for guests who follow medically prescribed diets for food allergies, Celiac Disease and/or Non-Celiac Gluten/Wheat Sensitivity.

UCSB Conference Dining & Catering must receive advance notice by a minimum of two weeks prior to the conference arrival date if a restricted diet accommodation at a catered event is required. For special meals catered through approved external vendors such as Kosher preferences, advance notification by July 15th is required. Please email Eriko MacDonald, Conference Dining Manager, with the details of your request.
