When planning to travel on a budget while cheap travel options such as cheap airplane tickets, discount hotel rooms, and cheap auto rentals can prove invaluable, there are additional steps you can take to ensure that you do not end up spending way more on vacation than you expected. The following is one money saving tips to consider. When is the best time to book your car? As soon as you know your dates. Unlike airline tickets, rental car reservations can usually be canceled without a penalty. So if prices drop—as they often do—there’s no reason you can’t cancel and rebook at a cheaper rate. The best strategy is to book as early as possible, and then keep checking to see if prices go down. We know it can be a chore to constantly check for lower rates so you don’t miss an opportunity to save money.
