3 Real Kids Birthday Party Budgets
1. The simple at-home party: about $350 + food
A 4-year-old, 10 friends, your living room. One character (say, a princess or Paw Patrol) runs a 1-hour program of games, dancing and a cake moment. Entertainment: $350. Pizza, a bakery cake and juice for 10 kids and their parents typically add $120–$200. You host, you clean up, but the hour of chaos has a captain.
2. The "big group" party: about $700–$950 + food
A 6-year-old, 18 kids from class plus siblings. Option A: two characters for 1.5 hours at your place, $700. Option B: Party + Entertainment at Lemur Lulu, $700 for the room and a 1-hour show, plus a $250 bubble show if you want an opener. Total: $700–$950. With 18 kids, the venue is often the better deal, because the mess stays out of your home.
3. The all-inclusive party: about $1,100–$1,500 + food
An 8-year-old, 25 guests, and you want it to look like Pinterest. The Full Experience at Lemur Lulu: 3-hour private room, a show or workshop, and a decor package with two wooden backdrops for $1,100. Add a paper show finale (+$250): $1,350. Add an hour of face painting as well (+$200) and you are at $1,550. You arrive, you celebrate, you leave.
Party at Home vs. at a Venue: Which Costs Less?
For small groups (under about 12 kids), home is cheaper: you pay only for the entertainer. Once the guest list passes about 15 kids, or if you are hosting between October and June when outdoor plans are risky, a venue package often costs about the same as the "hidden" costs of hosting at home: extra tables and chairs, cleaning, and a lost weekend. Compare:
- Home, 2 characters, 1.5 hours: $700, plus your setup and cleanup.
- Lemur Lulu Party + Entertainment, 3 hours: $700, with the room, tables, chairs, tableware and tea included.

Costs Parents Often Forget
- Food for the adults. In the Seattle area, most parents stay for the party. Plan food for them too.
- The cake. A bakery cake for 15–20 kids often costs $60–$150, more for custom designs.
- Party favors. Typically $3–$8 per child. Tip: a Make & Take workshop gives every child something to take home, so it doubles as the favor.
- Decorations. DIY balloons and tableware run $40–$100; professional styling starts around $350.
- Venue overtime. Many venues charge for every extra 30 minutes. Lemur Lulu's 3 hours are generous on purpose.
- Travel fees. Our prices cover the Greater Seattle area. Travel well outside it, extra hours or extra characters are quoted in writing before the party.
How to Save Money on a Kids Birthday Party
- Book one hour, not two. For kids under 6, a tight 60-minute program is better than a long one anyway.
- Pick a weekday or Friday evening for more flexibility with dates and times.
- Let the entertainer be the decor. A great character makes the theme; you do not need a balloon arch too.
- Use a park shelter in summer and pair it with a mobile show.
- Book early. You get your first-choice date and avoid last-minute premium options.
How Booking and Payment Work
You can build your party online: choose the show, the number of characters and the length, and you see the total instantly. A $50 deposit holds your date and is deducted from your total. The balance is due on the party day, before the program starts. The deposit is fully refundable if you cancel at least 7 days before the party. Prefer to talk it through? Use the "Talk to an event coordinator" option on the deposit step and our team will call you.
