#1 · Balloon garlands and photo backdrops, including DIY pickup
Poptastic Parties
Poptastic creates arches, garlands, backdrops, balloon drops and custom installations. Its Grab & Go garlands are ready-made for customers to collect and hang themselves, making this the most budget-friendly way to get its signature look.
Pleasanton; serves the Tri-Valley and wider Bay Area
- Grab & Go garlands from $150
- Custom installations from $650
- Allow two to four weeks for most parties
The catch: A full installation starts at $650. Heat, direct sun and wind can affect outdoor balloons, so summer park parties need shade.
#2 · Backyard bounce-house parties
Bouncy Bounce
Bouncy Bounce supplies bounce houses plus tables, chairs, canopies and other practical party rentals. Online booking makes it easy to assemble the activity and the basic backyard setup in one order.
Pleasanton; free delivery to the five Tri-Valley cities
- Bounce houses from $199
- Tables from $12, chairs from $3 and 10-by-10 canopies from $65
- Orders without a bounce house have a $50 delivery fee
The catch: The company does not set up in parks. You need flat grass, concrete or asphalt within 50 feet of an outlet and 17 feet of height clearance.
#3 · Styled, photo-ready backdrops
Petalloons by Balloonista
Petalloons combines balloon garlands with flower walls and themed backdrops. Its catalog includes 3D arches, rainbow and moon-and-cloud designs, shimmer walls, sequin walls and children's themes such as Under the Sea and Pink Butterfly.
Serves Pleasanton, Danville, Walnut Creek and the wider East Bay
- Pricing is provided by quote
- The company says inquiries receive a reply within 24 to 48 hours
The catch: Deposits are non-refundable, though cancellations receive a credit valid for one year. Confirm service before booking in Dublin, Livermore or San Ramon.
#4 · A sleepover party at home
Sleepy Teepee Party
Sleepy Teepee Party transforms a living room with junior mattresses, bedding, lanterns, rugs, fairy lights, themed decor and breakfast trays. It is a complete activity and decoration package for children who want a home sleepover rather than a venue party.
Oakland; serves the Bay Area
- Two guests from $400
- Up to four guests from $500
- Packages rise to $850 for eight guests; additional teepees after nine are $125
The catch: A $95 travel fee plus a per-mile charge applies, which can add up from Oakland to the Tri-Valley. Confirm that your city is covered.
#5 · Large backyard parties needing shade, tables and seating
LV Event Rentals
LV Event Rentals provides tents, shade structures, tables, lounge furniture and lawn games, with delivery or warehouse pickup. Its inventory suits a larger backyard celebration where practical seating and shade matter more than character-themed decor.
2135 S. Vasco Road, Livermore
- Pricing is by quote
- Allow one to two months from May through October
- Small last-minute orders can sometimes be prepared within 48 hours
- A 50% deposit is refundable when cancellation is more than 30 days out
The catch: The catalog is geared toward weddings and corporate events rather than children's themes. Early-morning, late-night and Sunday deliveries cost extra.
Tri-Valley park decor rules to check before booking
Pleasanton parks prohibit inflatables, dunk tanks, zorb balls, amplified music, silly string and chalk, and decorations cannot be attached to trees or structures. Danville parks also prohibit inflatables, jump houses, petting zoos and dunk tanks. Dublin permits bounce houses only in reserved picnic areas A, B and C at Emerald Glen Park. Sycamore Grove in Livermore prohibits piñatas, confetti, water balloons and inflatables. East Bay Regional Parks rental facilities prohibit confetti, glitter, streamers, poppers and bubbles, and balloons cannot be released outdoors.
- Foil balloons are being phased out in California beginning in 2028; helium foil balloons must already be weighted.
- Heat, direct sun and wind are hard on balloons. Ask about shade and schedule installation close to party time.
