Short answer: In New Orleans, book a bounce house 6 to 8 weeks ahead for spring and Carnival dates, 4 to 6 weeks for summer, 3 to 4 weeks for back-to-school and holidays, and 6 to 10 weeks for October school and church festivals.

I've been staking units across Jefferson and Orleans Parish since 1992. The call I get most often is a mom nine days out from a Saturday in April, asking for the unit her son saw at a friend's house.

I can almost always put something in her yard. I usually can't put that in her yard.

Lead time isn't about our schedule. It's about how narrow the calendar is here.

How far in advance to book a bounce house, by season

Here's what I'd tell my sister.

If your event runs through a school, church, or company, add two weeks. Approval takes longer than the reservation.

Why does the New Orleans calendar compress so badly?

Because every school in Jefferson and Orleans Parish wants the same four Saturdays.

Take October. Between the first cool front and Halloween there are about four usable weekends, and in that window every school from Kenner to Algiers Point, every church in Metairie and Mid-City, and every group in Lakeview and River Ridge holds a festival.

They aren't coordinating. They're reading the same weather.

Spring does it too: Easter moves, crawfish season peaks, field days land between mid-March and mid-May. Our inventory doesn't expand for those weekends. Neither does anyone's.

What does "sold out" actually mean?

It almost never means we have nothing. Three versions:

1. The specific unit is booked. The deluxe themed combo your daughter wants. There is one of it, and it's what's usually gone.
2. The category is thin. On a hot June Saturday most water slides are out, but a wet/dry combo does the same job for a 5-year-old.
3. The truck is full. Rare, mostly an October routing problem. An early drop usually solves it.

So when you hear "that one's booked," the useful follow-up isn't "are you sure." It's "what's open in that size?"

Does booking early cost anything extra?

No. We don't price by lead time. A unit costs the same in January as the Thursday before.

You pay a deposit: $50 minimum on orders under $500, or 25% over $500. Deposits are non-refundable but convert to a raincheck for a future date.

So the downside of booking six weeks out is holding $50 with a company that will honor it if a storm rolls in. The downside of waiting is taking what's left.

Lock the date, change the theme later.

What can I actually get on 48 hours' notice?

More than you'd think in February. Almost nothing you'd choose in October.

Usually available:

• Standard bounce houses in the common sizes
• Toddler and kiddie bouncers, which turn over less
• Tables, chairs, carnival games, foam machines
• Weekday setups

Usually not available:

• Water slides from May through September
• Themed combos on any spring Saturday
• Obstacle courses and the 26-foot rock climbing wall
• Park setups, which carry a $500 delivery minimum and often a permit
• Full party packages with multiple units on one truck

One note on rush orders: concrete and asphalt need sandbag ballast instead of stakes, and that gets loaded ahead of time. Tell us at booking.

Is a weekday easier to book than a Saturday?

Considerably. Roughly 80 percent of residential demand lands on Saturday, most between 11 a.m. and 3 p.m.

Sunday afternoon stays open even in peak spring, and Monday through Thursday I can usually deliver on a few days' notice year-round. That's why summer camps and midweek school fairs rarely have an availability problem.

If your date is flexible, moving to Sunday beats calling ten companies.

Should I book today?

Book today if your date is:

• Any Saturday in March, April, or May, especially Easter weekend
• An October school or church festival. Ten weeks out isn't early. It's on time.
• A June or July date with a water slide. Wet inventory goes first.
• A Carnival party on a parade route, where closures limit access
• A date where one specific themed unit is the whole point
• A park or commercial venue, where permits and the $500 minimum take time

Weekday, Sunday, or late August through September? Three weeks is fine.

Frequently asked questions

How far in advance should I book a bounce house for a birthday party? Four to six weeks for most backyard parties, and 6 to 8 weeks if your date is a Saturday between March and May. Back-to-school and holiday dates are easier, where 3 to 4 weeks is usually enough to get the unit you want.

Can I book a bounce house a week before my party? Often yes, for a standard bounce house on a weekday or in an off-peak month like February or November. But a week's notice on a spring Saturday or in October means taking whatever is open rather than choosing what you want.

How far ahead do schools and churches need to book fall festivals? Six to ten weeks. Every school in Jefferson and Orleans Parish competes for the same four October Saturdays, and institutional orders need approval time before a reservation is real. Once your committee picks a date, reserve units before the flyer goes out.

What deposit do I pay to hold a date? A $50 minimum on orders under $500, or 25% on orders over $500. Deposits are non-refundable, but they convert to a raincheck for a future date if weather forces a cancellation. There is no surcharge for booking months in advance.

Is Saturday or Sunday easier to book in New Orleans? Sunday, by a wide margin. About 80 percent of residential demand lands on Saturday between 11 a.m. and 3 p.m. Sunday afternoons stay open even during peak spring, and Monday through Thursday is nearly always available on a few days' notice.
