The Preteen Party They've Been Waiting For

You know the dilemma. Your kid is turning 9, 10, 11 — somewhere in that in-between stretch where they've completely outgrown the bounce house era but aren't quite teenagers yet. They want something that feels cool. Something they can actually tell their friends about. Something that doesn't make them feel like a little kid.
Finding that? Surprisingly hard. Until now.
Wonder Childhood Discovery in downtown Leesburg — the award-winning play and discovery space that Loudoun County families have been raving about — just launched a brand-new preteen party experience. And it hits exactly the right note: energetic without being chaotic, engaging without being overwhelming, and designed with the specific social needs of this age group front and center.
Energetic without being chaotic. Engaging without being overwhelming. Their party, their way.
Who is this for, exactly?
Wonder's preteen parties are designed for kids ages 6–12 — that sweet spot where childhood magic is still very much alive, but the vibe needs to feel a little more grown-up. There are no firm age restrictions, and Wonder's team can tailor every activity to fit your group perfectly. Whether your kid is a STEM obsessive, a Swiftie, an adventure-seeker, or a creative soul, there's a party built around them.
What Makes It Different
Wonder's preteen parties are built on the same DNA as their wildly popular toddler celebrations — except leveled up for older kids. Every two-hour party is fully customizable: you select from ready-to-book themes or design something completely original with Wonder's party planners at no extra cost. The whole space is exclusively yours during your party, closed to the public, so your group has the run of the place.
And the best part for parents? Wonder handles everything. Setup, facilitation, cleanup — their dedicated team manages it all so you can actually be present and enjoy the celebration instead of running it. You show up. They do the rest.
The Three Packages
Wonder offers three distinct preteen party packages, each designed for a different vibe and budget. Every single package includes exclusive access to the space, dedicated Wonder team members, balloon garlands, paper products, mini water bottles, a personalized welcome sign, a group Polaroid photo, and a 15% retail discount for party guests.

Good to Know Before You Book
How far in advance should I book?
Wonder recommends booking at least four weeks ahead to secure your preferred date and time — weekends fill up fast, especially for the new preteen packages.
Can I bring my own decorations and party favors?
Absolutely. You're welcome to bring additional décor, and Wonder's team will set everything up about 15 minutes before your guests arrive. Party favors are welcome too — the team will help hand out gift bags at the end.
What if I need to cancel or reschedule?
In the case of snow or severe weather, Wonder will work with you to move your party up to two times at no cost. Note that a $150 deposit is non-refundable, so plan ahead!
Can I split up the party cost into payments?
Yes — Wonder is happy to work with you to divide payments over time. Just reach out to contact@wonderleesburg.com to set that up.
Not sure yet? Can I tour the space first?
Wonder offers free birthday party consultations and facility tours so you can see exactly what you're booking. Schedule one at wonderleesburg.com/preteenbirthdays — no commitment required.
Booked a party before? There's a reward for that.
Repeat birthday families get a special thank-you — choose from a discount, a sensory dough birthday add-on, or two free cheese pizzas. Just email Wonder to claim it.
