Travel costs refer to the expenses incurred when planning and undertaking a trip. These costs can include transportation fees, such as airfare or gas for driving, as well as accommodation expenses for hotels or rentals. Additionally, travelers may need to budget for meals, activities, and travel insurance, which can vary based on the destination and duration of the trip. When estimating travel costs, it is essential to consider factors like the time of year, as prices can fluctuate during peak seasons. Using tools like travel comparison websites can help travelers find the best deals on flights, hotels, and car rentals to manage their budgets effectively.
