It's not entirely down to scheduling conflicts and availability in the photo area, the driving force is that the guests have to agree to do it. It may not be that they haven't, I'm just pointing out that group shots aren't only determined by those factors.
totally got the point that can avoid group shoots but still cant understand it mostly, esp. because they are doing there single shoots all after in a row and except chapman all done conventions with group shoots. the only reason would be that one of the three guests would decline, would suprise me if this is the reason in that case
in my opinion group shoots are really highlights for most events/conventions as its rare that reunions come together that way and to be fair its simple normal to most events. I got the hellraiser group shoot in 2011 at LFCC with clive barker and its still one of my best moments ever. as said it would be easy here, even getting tickets for all single shoots and just combine them at the end of there single shoots as they are straight after
no complain at all but something to think about for all future events as I often thought why they didnt offer group shoots like for the BTTF reunion in 2015, or some great other reunions showmasters already had
