The rental car I booked on Kayak was not available at Budget on Guam bc somehow Kayak booked my car for Saipan instead. When we got to Guam, Budget said they had no more cars available and weren’t able to move my Saipan reservation to the Guam location. Thankfully the nice staff at Budget called around and found a car available at another car rental agency otherwise we wouldn’t have had a rental to get around. We won’t ever use Kayak again for rental cars. BTW, Budget staff as well as a military member said this is a common occurrence - that people book online on Kayak only to arrive and find out their car was booked on Saipan instead. Kayak should know that Guam and Saipan are two different islands. Terrible experience booking a car through Kayak but kudos to the Budget staff for helping us find another option.
