Use a mapping app to sketch a true 50-mile radius, then mark parks, libraries, markets, and low-cost attractions in three clusters. Clusters reduce driving and protect the budget. Add two backup micro-stops per cluster, like a playground or viewpoint, for flexibility when naps, weather, or energy levels shift unexpectedly. Keep parking notes, bathroom spots, and shaded rest areas flagged.
Allocate roughly 40% for transport, 40% for food, and 20% for activities or treats, then adjust based on free-entry days and transit passes. Pack water, fruit, and a protein option to avoid impulse buys. One family spent $12 on bus fare, $18 on shared tamales, $10 for canoe rental, and $8 on popsicles, creating four hours of joy and zero complaints.
