How many people do 3 bags of ice cover?

20-lb bags

Covers about 60 people indoors, or 30 outdoors in warm weather.

Everything else for 20 people

How we got this number

  1. 120 guests × 1 lb (indoors) = 20 lb
  2. 2× 1.10 cushion = 22 lb
  3. 3÷ 20-lb bags = 1.1 → 2 bags (20 lb)

we round up to whole bags. Ice is cheap; running out isn't.
