What size cooler is best for two people for a weekend trip?

A 50-quart cooler is the sweet spot for two people for a weekend. It gives you room for three days of food, drinks, and enough ice to last until Sunday. Smaller coolers like 30 quarts leave you cramming or running out of ice, while bigger ones are too bulky. Pack smart with pre-chilled items and block ice, and any decent rotomolded cooler will work.
