Fair point, dwshimoda, and I'll pass it on.
Groups organising fly-ins can come to Duxford and benefit from landing fee discounts and museum entry discounts by prior arrangement on most days of the year -- except when there are other major events on, where space would be an issue. Prior arrangement with the Airfield Manager, Frank Marson, is needed. If anyone would like to pick up the reins and orgainise a PPRuNe fly-in, give Frank a call first -- 01223 499337.
The bonus days are designed to be extra, over and above fly-ins, but I take your point that 'Cessna' and 'Piper' Bonus Days may mean friends can't join in on an equal basis. The following two fly-ins are for Taildraggers and Students.
Alternatively, borrow a Piper
