There are not PhotoPass photographers at either Tusker House or Crystal Palace.
Only a handful of character meals have photographers, and then only for specific characters. There's one for entry at Akershus and CRT, Stitch has one at 'Ohana breakfast, a couple like that.
Character handlers will take pictures for you using YOUR camera. But that's not PhotoPass.
And no, you can't request PhotoPass at either TH or CP. They aren't staffed there.
