Should I buy a rotomolded cooler for a day at the beach?

No, rotomolded coolers are overkill for a day at the beach. They’re heavy, expensive ($200+), and hard to carry, while a basic injection-molded cooler like a Coleman handles a weekend trip fine for $40. The rotomolded advantage—longer ice life from seamless construction and thicker insulation—only matters for off-grid camping, direct-sun tailgates, or rough handling. Save your money if you only need drinks cold for a few hours.
