All buses/vans must arrive at the Main Gate for security processing. Buses will be met at the Main Gate by a Dover AFB Tour Ambassador who will accompany the group onboard the bus and will remain with them for the duration of the tour. If a group is running late due to unforeseen circumstances it is the group's responsibility to contact our Public Affairs office, at 302-677-3408 or 302-677-3487 to see if adjustments can be made to the tour itinerary. If a group does not contact the Public Affairs office and is more than 15 minutes late for their tour, the tour may be cancelled. If a tour is cancelled, it may be rescheduled for a later available date.
