Here is a great package for a day out on the Peninsula.  Use your four VIP passes to visit the Hiller Aviation Museum in San Carlos which specializes in Northern California aircraft history and helicopter history.  This museum has more than 45 aerospace vehicles along with companion descriptive displays concerning the history of flight.  The Hiller Aviation Institute is dedicated to the dreams of flight - looking back into aviation's history while exploring its future. The experience is educational and entertaining casting new light onto the technical innovations. Before you leave, you'll be transformed from visitor to explorer.   Afterwards, stop at one of Amici's many Bay Area locations and treat your foursome to a family-sized pasta platter!  Choose from favorites like pesto, marinara and four-cheese lasagna.  More info here http://www.hiller.org/ and http://www.amicis.com/
