Be aware that for shots like Captain Hook and Darth Vader, you may have to hunt around to find a photographer that can do the shot since Vader and Hook require a lightsaber and sword prop. I asked for 3 straight days about the Vader shot and on the 3rd day, they called and found somebody in the park that could do the shot. The CM who took my shot told me that the Vader shot is somewhat rare, so if you really want it, you should probably ask for it at Photo Supply on the end of Main Street.
There's also a Haunted Mansion ghost shot, Mickey or Minnie sitting on a bench, or Stitch breaking through the pavement. The best piece of advice I have is that you want a certain shot, ask a PhotoPass CM about it. Even if they're not equipped to take it, they should be able to direct you to someone who can.
