Dignitaries invited to present or attend a conference most often do so with the understanding that expenses incurred for travel, lodging, and perhaps payment of an honorarium will be covered by the conference budget.
Once a VIP has been invited and their participation has been confirmed, we communicate directly with that person to assure that they are at the right place, on the correct date, at the correct time. We book their travel (flights and ground transportation), reserve their hotel room, and schedule ground transportation from an airport to the conference site (as well as the return trip).
