Hertz was great, my review is more about making a booking through Kayak instead of with Hertz directly: Making a booking with Kayak means you have no flexibility to make adjustments - so make sure you book exactly what you will need. You lock in a rate and dates, and then there is no way to adjust your booking. You can’t add or remove days, you can’t switch your drop off location. Hertz has no ability to make adjustments to your booking because it was made through Kayak at a guaranteed rate - and Kayak also can’t adjust your booking because you are technically booked with Hertz. We had extremely kind and helpful service staff with Hertz who couldn’t do anything to adjust the booking. I booked for six days and later wanted to add a seventh, they couldn’t do it even though the “weekly rate” would have technically covered the seventh day and no more money would have been exchanged. I even offered to pay for the extra day, and Hertz couldn’t do it - they literally cannot change any numbers in their system once the booking is made. I would book through Kayak again, it was easy to use and the rental price was a good deal, but I will be more careful and only book if I am 100% confident on the dates I need.
