A good corporate trip alternates between content and relaxation. The rule of thumb: a maximum of six hours of programme per day, with clear blocks for work and switching off.
Schedule substantive sessions in the morning, when everyone is sharp. Reserve the late afternoon or evening for social activities or free time. One half-day without programme every two days works best.
Announce those free moments in advance in the itinerary, so attendees feel they have room to breathe.
