What changes at 20 guests

An intimate group like this fits in a house, a private dining room or a small venue. With only 4 tables, one delivery and a two-person crew can usually set the room quickly, and a statement chair style is affordable because the total quantity is small.

Planning a backyard party

A backyard is smaller and less level than a venue, so measure first. Rounds of 6 or long picnic-style tables often fit better than rounds of 8.

Chairs on lawn need wide feet or protection. Lightweight outdoor-friendly styles are easier to carry through a side gate.

Delivery access matters: a narrow gate or a long walk from the street affects the crew and the timeline.

Mistakes to avoid

  • Not measuring the gate and path.
  • Setting the party in full sun with no shade for guests.
  • No rain plan for a party that needs everyone indoors.
