Before You Book
Hosts usually book party supply and balloon stores 1–2 weeks ahead for custom balloons. Ask:
- Do you offer helium balloon fills, and how long do they float?
- Can you make custom balloon arches or garlands, and do you deliver?
- Do you take orders by phone or online for pickup?
- What is the return policy for unopened items?
- Do you rent any items (backdrops, stands, costumes)?
Booking Tips
- Order helium balloons for pickup on the day; latex balloons often float less than a day.
- Buy tableware for about 10% more guests than your RSVP count.
