[Captain America / Avengers] Stories of Various People and a Ticket for a Photo with Captain America

Several unrelated people and a photo-op ticket for a picture with Captain America at an Avengers theme park. This story came from a sudden idea. The main premise is that there is an Avengers theme park, something like Disneyland, with an attraction similar to Disneyland's "Photo with Captain America" experience. Of course, the Captain America in the photo is played by an actor. It's probably something of a half-AU (?), so feel free to imagine the timeline however you like. The setup is simply that Cap is still looking for Bucky, while Bucky has escaped Hydra but hasn't recovered his memories yet and hasn't left New York. The pairings include Steve/Bucky or Bucky/Steve, no preference; Stony; and a familial Peter/Tony relationship. Theme:
