Horrible service and FRAUDULENT at best. We made an original "mystery car" rental 4 weeks ago through Holiday Autos with Dollar Car Rental in SFO. In the booking it fully states a free additional driver is included, along with sales and tourism taxes. It is also a mystery vehicle that would comfortably seat 5 people and 3 suitcases. When we showed up to the desk very late in the evening for our pickup, we were given a pickup truck for 4 people, with no room to safely secure our suitcases. We then had to upgrade on the spot. They also would not provide the additional driver for free, as per what was advertised - stating that it was not their issue there were discrepancies on the third party payment platform. Lastly, they will try to upsell a $59 unlimited toll pass for the week, which really isn't necessary if you aren't intending to drive a lot while in town. They took a $289.95 USD booking and made it $754.59 USD... we could have easily found a new booking for under $500 USD with a premium rental company! BEWARE AND STAY AWAY IF YOU WANT A SMOOTH TRIP!!!!!!!
