Day 15: Host Tip – How to Prep Guests So They Arrive in Character

Hero Image

Welcome to Day 15 of our 31 Days of the Ultimate Halloween Mystery! We’re halfway through the countdown, and today we’re solving a mystery that every host faces: how do I get my guests to actually arrive in character?

Your murder mystery party only comes alive when your guests slip into their roles. The accents, costumes, and dramatic one-liners — those are what turn your living room into a haunted mansion, a spooky speakeasy, or a sinister ski lodge. But some guests need a little nudge before they’re ready to play detective (or suspect). That’s where a few murder mystery party host tips can set you up for success.


The Challenge: Guests Don’t Always Know Where to Start

Even with the best intentions, guests sometimes feel nervous: What if I don’t dress right? What if I don’t “act” well? Without guidance, they may show up underdressed, unprepared, or too shy to lean into their role.


The Solution: Set Them Up for Success Before the Doorbell Rings

1. Send Out Character Sheets Early

Timing is everything. Send your guest their character sheet at least a week in advance (two weeks is even better). This gives them plenty of time to read their backstory, absorb their objectives, and brainstorm a costume.

Night of Mystery Bonus: Each character sheet already includes acting tips and costume suggestions — so even if your guests aren’t natural performers, they’ll have a cheat sheet to help them shine.


2. Make Costumes Easy (and Fun!)

Not every guest has a full costume closet, so remind them they don’t need to spend big bucks. Share a couple of simple, low-cost ideas that tie directly into their role:

  • A detective just needs a trench coat and notepad.
  • A diva can rock sunglasses and bold lipstick.
  • A villain? All black with a dramatic accessory.

Encourage them to use what’s already in their closet and add one or two props. The Night of Mystery character sheets highlight affordable suggestions, so lean on those when you send your invites.


3. Encourage a Little Practice

Guests don’t have to memorize lines — but a few mannerisms or catchphrases can boost confidence. Suggest they:

  • Greet people in character (e.g., “I hope no one here knows my secret…”).
  • Use a simple accent if they’re comfortable.
  • Think of one or two conversation starters to help break the ice.Guests Acting In Character.

4. Send a Warm-Up Message

When you email the character sheets, set the mood with a little flair. Here’s a copy-paste friendly example:

Subject: Your Secret Role Awaits… 🕵️‍♀️🔮

The countdown is on! At our upcoming murder mystery party, you’ll be stepping into the role of [Character Name].

📜 Your character sheet (attached) includes:

– Your backstory & secrets
– Acting tips to bring the role to life
– Easy costume suggestions

A little prep goes a long way — the more you get into character, the more fun you (and everyone else!) will have. Can’t wait to see what you bring to the game!


Common Mistakes to Avoid

Even seasoned hosts sometimes trip up. Here’s how to dodge the pitfalls:

  • Sending info too late – If guests only see their roles the day before, they won’t have time to prep.
  • Assuming everyone will DIY perfectly – Always provide costume shortcuts and personality cues.
  • Not hyping the fun factor – Remind guests this isn’t about “acting skill.” It’s about being silly, playful, and immersive.

Why This Matters for Your Party

These hosting murder mystery tips don’t just make life easier for guests — they elevate your whole event. When characters walk through the door fully costumed, secret objectives in mind, and ready to banter, your job as host gets 100x easier. Instead of coaxing shy participants, you’ll watch as the story unfolds naturally, with laughter, accusations, and shocking twists filling the room.


A Mysterious Wrap-Up

By giving your guests the right tools, encouragement, and a little extra time, you’re not just throwing a Halloween party — you’re creating a one-night-only immersive experience they’ll never forget.

Tomorrow, we’ll swap costumes for cauldrons and share a frightful feast recipe that will leave your guests howling for seconds. Stay tuned!
