The biggest causes of fluctuation in tour bus pricing are bus type and time, which includes not only the duration of your trip, but time of year and day, as well. Generally speaking, peak tour season will see a surge in pricing, as will nighttime rentals, given that drivers are typically paid a premium after dark. Time is on your side once again, as most tours can be completed in a day. However, if you’re planning a longer, out-of-town tour, your rental cost may include accommodations for the driver.
