Renting with Kelly was a great experience. The van was clean, brand new and maintained well. We were even allowed to pick it up the night before our scheduled time because of conflicts in our schedule!
We ended up driving the van way more than intended and they were very flexible and understanding when we ended up doubling the permitted mileage. Will definitely rent from them again if the need arises.
