By setting a budget, travelers can manage their finances effectively and avoid overspending. Creating a travel budget involves estimating costs for each category and comparing them to your available funds. This helps ensure that you can enjoy your trip without financial stress. Tools like spreadsheets or budgeting apps can assist in tracking expenses and staying within your budget during the journey.
