Arrival times, hmmm, anytime you like really, I remember the last one got really busy around 1130 and we were told to space out a bit.
As for lunch, you just get what you want when you want it and eat outside on the tables if you like. There will be lots of people just milling about outside the clubhouse chatting, just look for the pprune badges, caps etc.
Make it 29th August & I'll buy the teas.
an offer made by our good friend
Kolibear 
Don't forget it is free landings, just mention your with the pprune fly-in and make a donation, I think a fiver, it is for a good cause, the Bader foundation.
Fingers crossed for decent weather!
