Use a general travel-planning website, such as Hotels.com, to check conversion van prices in your area from the major car rental companies, if any are available. Select "Minivan" for your class preference. Then, look for quotes from a local rental agency. The Conversion Vans website has a rental search and includes links to several regional providers. Look for the headline "Van Rental Companies in Smaller Markets Listed Below" within the rental section on the website.
Look at the daily rate of conversion vans to see which company has the lowest daily price.
Find out the proposed the taxes and fees on each quote. The company with the lowest daily rate may have the highest taxes and extra fees, which will bring up the price.
Review the mileage allowance included with the rental. Typically, you can get unlimited mileage, but some rental companies may charge per mile. Depending on the distance you're planning to travel, this can make a difference in the amount you pay for the rental.
Calculate the insurance cost, if you plan to get the rental company's insurance for the van. Or check with the company that insures the cars you already own to see if a conversion-van rental is covered under that policy.
