Rotomolded cooler vs cheap cooler: Rotomolded is the only real option for 5 days

Cheap Coleman or Igloo coolers keep ice for maybe two days in summer—then you get lukewarm water and spoiled food. Rotomolded coolers like Yeti or RTIC have thick, insulated walls that hold ice for days or even a week if pre-chilled and shaded. You don’t need the most expensive brand; RTIC and similar knockoffs work nearly as well for less. For five days without resupply, this is not where you go cheap.
