I was planning to rely on Uber, but realised that renting a car might be worthwhile. I am traveling today and all car rental websites I know only provide rentals in 3-4 days from now.
Is my only solution to check on arrival, or can I still check options online for car rentals today? I don't have phone access, but I do have some flight connections, where I will have some time to search for options.
So my question boils down to, can I book a car online today at San Diego airport?
