What Our Customers Are Saying
Party Baby came through for me in short notice planning of my little girl's birthday party. I rented the mini castle bounce house and ball pit to set up at pur house and it was amazing! It was the perfect set up for our backyard and age group of kids (2-6). Everything from communication, transparency of pricing, ease of set up, experience using the product and takedown was seamless. Everything was super clean and looked new. Would absolutely recommend and use again. Thank you, Party Baby!
EVERYTHING WAS ALL PERFECT!!!!! THE KIDS LOVE IT AND THEY HAD AN AMAZING TIME WHEN I RENTED THEM FOR MY DAUGHTER'S FIRST BIRTHDAY. When you do the consult, they will walk you through. They have been very patience with both my husband and I. They are such wonderful teams. This was my first time with them too. I most definitely will do this again in November for my son's 5th birthday!! Go check them out yall.
Super easy communication and getting it scheduled. They came and set it all up and then took it all down at the end. All the kids and adults loved the castle bouncy house.
Awesome customer service! We great a wonderful experience
We rented the bubble house from Party Baby for our wedding reception, and it was absolutely perfect. We had a large rooftop space to fill and a lot of kids attending, so I wanted something that would help keep everyone entertained — and it ended up being a huge hit with both the kids and adults. The kids especially loved it and spent so much time playing in it throughout the reception.
I’m only posting one photo because I’m shy, but honestly we got so many amazing photos and videos with it. It added such a fun energy to the reception and looked great in the space.
Working with Jeannie and the team was also incredibly easy. One quick phone call was enough to get everything set up, and the staff onsite was friendly, professional, and very kind to our guests.
Highly recommend if you want something memorable and fun for a wedding or event — you won’t regret it!

Party baby was fantastic! Great set up, great communication and reasonable prices.
As a social event planner, I worked with Party Baby this past week for a client’s son’s birthday party. Jeannie was so easy to work with, adhered to our color palette requests, and set-up according to our timeline. The play-set was a huge hit with the kids and fit perfectly with our spring chicken theme. I highly recommend Party Baby and would use their service again in the future.
Fantastic experience and it was the highlight of the party!! The team was responsive and helpful. They showed up right on time and got everything set up. Everything they provided was perfect and I will absolutely be using them for parties in the future!
We chose the cotton candy package from Party baby Seattle . It perfectly matched our pastel color scheme, I appreciated the options to customize the colors , set up and take down was taken care off well and most importantly, the kids loved it !
South Lake Union Party Rental FAQs
-
-
Yes, South Lake Union is part of our regular delivery area, including SLU, Denny Triangle, Belltown, Eastlake, and nearby Downtown Seattle neighborhoods, with delivery, setup, and takedown included with every rental.
-
-
Yes, park events work beautifully. Inflatables need power, so park bookings run on a reliable generator, and the shelter or picnic-area reservation with the city is handled by you before the event. Lake Union Park is a local favorite for exactly this.
-
-
White bounce houses, soft play for ages 1 to 5, and ball pits with ball colors matched to your theme lead most South Lake Union bookings, for birthday parties, first birthdays, corporate family events, and venue celebrations.

-
Trusted by the Seahawks, Mariners, Salesforce, and Google, we deliver kid friendly corporate events, daycare and school events, and employee family days at South Lake Union workplaces, offices, schools, and venues. See corporate events for the full picture.

Yes, indoor setups run year round in offices, event venues, community rooms, play spaces, and apartment amenity rooms, which is how South Lake Union families and teams keep winter celebrations going. We never set up outdoors in the rain, so an indoor backup is always the smart plan.

Seattle Mariners Family & Friends Day at @tmobilepark.
The game ended, and our team had exactly 30 minutes to build a custom soft play setup on the field before the players walked out with their families, still in their jerseys.
Custom @seattlemariners ball pit, team color palette throughout, and stacking cubes with custom decals. Built for the littlest fans in the ballpark.
Thank you to the @seattlemariners for having us. Getting to be part of a day like this for the players and their families is something we won`t forget.
