I know that Mark Hamill who plays Luke Skywalker charges an awful lot for his photo/autograph, but so does Daisy Ridley who plays Rey. It would be cool to meet them in cosplay: his Jedi robes and her Resistance base outfit in person respectively. If they appeared together at San Diego Comic Con that would cost you a hefty amount of money all at once. I mean, don't think I am trying to start any rumor about them appearing together at a convention. Thank goodness there are likely to be opportunities to see them separately down the road for different events. So in essence the option exists to see them paired together or individually at some point around the same time. It's six of one, half dozen to the other.
