ventureland I'd love to have her ex-boyfriend! Basically she broke up with him because she started to like Andy, and now he likes to regularly come to the park just to bug her, and there's been many times that she pulls pranks on him (ie - bribing a child to throw up on his foot, etc.). I think it could be fun to have him apply at Ventureland so then she can't escape him for too long since he'd be working with her.
I'm not picky about pbs, but Jackson Rathbone or Michael Angarano could work!
