I just wanted to let you all know about a super cheap way i've found to travel around california! I've just travelled from Los Angeles to Monterey and Monterey to San Francisco using this great deal!
Go to Holidayautos.co.uk through quidco. (£10 quidco, high tracking rate). Now you select a car hire from whichever city you want to start in to whichever you want to end in. Select to pick up the car 1 day and drop it off the next either at the same time of day, or earlier, as long as it is 24hrs or less). Price will be £17 for the 24hr hire.
Now, here's the neat part - select the 'MAX' option on the insurance part. for £4 Not only does this give you better insurance, but it gives you a FULL TANK OF FUEL FREE! For £4! They give it to you full, you return it empty!
I drove LA to Monterey on about 3/4 of a tank - 350miles. To tank up in the US will cost around $60 (£30), but you wont need to do this.
This is such a great deal that the person at the pickup desk couldn't believe it and had to call headoffice to check it was right - it was!
So, LA to San Fran can be done on 1 tank. Grey Hound =£50 , flight = £150, rent a car and see the amazing highway 1 coast ~£12.50!
Any questions about this, just give me a message. I've just done the route, it's fantastic!
p.s. car hire must be in the same state - if you pick up in 1 and drop off in another, you will get charged $199 one-way charge.
