This one-day reveal package includes accommodations for July 18th & 19th,
a private reveal watch party and dinner reception at our hotel Thursday night,
access to the Friday reveal festivities, a private lunch and tour of an area auto museum, bus transportation to and from the reveal activities, and the gift of a special event polo only available to those on this trip.
