We will have a better idea of the itinerary once we know for sure which guests are available when and for how long. I'm not really a fan of forcing folks to choose between a panel and a photo session, and we normally only have that kind of set up when the guest list is a large one...and guess what?!!
So we will try our best to keep it to a minimum, but yes, advance warning, it may well be the case that there are certain photo sessions going on while panels are happening.
As far as the auto session is concerned, that will take place on the Sunday afternoon once the panels have ended - though again if any guests are unable to attend on Sunday we will try to fit in an extra auto session if we can.
