Seattle Mariners Opening Week: Family Fun with Party Baby Seattle

Updated: Apr 17, 2025

There’s nothing quite like Opening Week at T-Mobile Park. The energy. The fans. The sense of anticipation. And for the second year in a row, the Seattle Mariners tapped Party Baby Seattle to help make the experience even more memorable—for the whole family—at their Opening Week Warm-Up event.

Last year, we brought our original bubble house to Opening Week, and it was an instant hit. Families waited over an hour just to step inside. Kids couldn’t get enough of the balloon-filled fun. It quickly became one of the most talked-about attractions of the day, proving that when you create space for kids at large-scale events, the payoff is real—for both families and the brand.

So this year, we came back even bigger. We brought one of our newest—and most eye-catching—additions to our corporate event lineup: the Double Bubble. Already a fan favorite at other events, this was its first appearance at T-Mobile Park. Set up in a prime location in center field, it immediately stole the spotlight.

Even with a larger footprint and a more streamlined setup, families were still lining up for over an hour to let their little ones play. They could explore and take photos in a sea of floating balloons. The response was overwhelming in the best way. The Double Bubble didn’t just meet expectations—it became one of the largest attractions of the Opening Week Warm-Up event.

From setup to teardown, our team managed every detail. We delivered a fully branded, clean, and professional experience that felt seamless for the Mariners and magical for their guests. For parents, it was a chance to relax and enjoy the event knowing their kids were having just as much fun. For the Mariners, it was a way to show fans—especially young families—that everyone is welcome.

These are the kinds of partnerships we thrive on. Whether it’s a major league opener, a company picnic, or a high-traffic community event, we design and execute family-friendly events that elevate the entire experience. They’re fun, safe, and on-brand. Most importantly, they create real, lasting memories.

FAQ


What are some fun ways to entertain kids at a corporate event?

Great kid-friendly entertainment options include soft play zones, bounce houses, face painting, bubble houses, interactive games, and activity tables. These are all popular choices at Seattle-area corporate events.


How do you make a corporate event family-friendly?

Designating kid zones, hiring experienced children’s entertainment, and offering age-appropriate snacks or activities helps create a more inclusive, family-friendly experience for employees and guests.


Are bounce houses appropriate for corporate events?

Yes, bounce houses are a great fit for corporate picnics, open houses, and company family days. Just make sure the bounce house is age-appropriate for the children attending. Companies like Party Baby offer a range of bounce house sizes and styles to suit toddlers, older kids, and mixed-age groups. This makes it easy to match the right setup to your event.

Bounce houses designed for younger children are typically smaller and take up less space, which means you can even rent multiple units for different age groups if space allows. For older kids or high-energy setups, consider something more adventurous like our Cloud 9 Adventure Course—a fast-paced inflatable experience that keeps bigger kids entertained and active.


What age range is soft play best for?

Soft play rentals are ideal for toddlers and children under 5. They offer a safe, enclosed space for active play at both indoor and outdoor corporate events.


Can we rent kid-friendly entertainment for indoor corporate events in Seattle?

Absolutely. Many options like soft play areas, ball pits, and activity stations are perfect for indoor use. They can be set up in lobbies, office spaces, or event venues around Seattle.


How do you keep kids of different ages entertained at a corporate event?

The best approach is to offer a mix of entertainment options tailored to different age groups. For example, soft play zones are ideal for toddlers, while bounce houses, games, and activity tables keep older kids engaged. Choose multiple products or stations to create an inclusive experience for everyone.


How do you make a corporate event feel memorable and Instagram-worthy?

Creating an aesthetically pleasing event space is key. Use well-designed setups, cohesive themes, and fun entertainment that photographs beautifully. Before hiring any vendor, check their Instagram or past event photos to see how visually strong their work is. This ensures the event is something employees are proud to post and share.


How much does it cost to rent kids’ entertainment for a corporate event in Seattle?

Pricing typically starts around $500 for small events, depending on the type of entertainment, event length, and number of children. Larger events often require more elaborate setups, multiple packages, and staffing requirements, which we can scale to meet your needs and budget.


What should I look for when hiring kids’ entertainment for a company event?

Look for vendors with experience in corporate event setups, who understand how to entertain kids while working within a professional environment. Bonus points for companies that offer flexible packages, have strong client reviews, and can share photos or videos from past corporate events.


What are the non-negotiables any kids’ entertainment vendor should have?

At a minimum, a vendor should be licensed, insured, and able to provide a Certificate of Insurance (COI). Safety should be a top priority, especially for events with children. Clear communication and transparent setup and teardown procedures are also essential.
