Hi – yes there is!
Ultimately this comes down to adjusting the width and spacing that is initially applied to those elements. So playing with padding and margin properties is also going to be required here – but something like this would basically give you 4 columns:
#tribe-events-photo-events .vevent.tribe-events-photo-event { width: 20% }
You could follow the steps here and add the above rule to a custom tribe-events-pro.css stylesheet.
Does that help?
