You can either book a venue that offers this service or host it at home by hiring actors and birthday event organisers who specialize in immersive events.
Set the tone with themed invitations, costume suggestions, and décor. Use era-appropriate party props for the 1920s, Victorian era, or modern detective-style themes. Combine this with a classy summer party theme idea like “Sunset Soirée with a Killer Twist.”
