My girlfriend and I are planning our first trip to the US from the UK with a fly drive from San Francisco to Las Vegas at the beginning of May. We are thinking of staying at SFO and Vegas for 3 nights each. The rest of the time will be spent driving between the two stopping off a Yosemite, Sequoia and Death Valley National Parks.

Could you recommend any budget Inns/lodge's were we could stay for a couple of days each along the way.

Also could you recommend any books on driving rules/laws/road signs etc for the US or/and California asI have not been able to find any.

Thanks for your help

Adam.
