hi! my friends and i are travelling to xi'an on march 29, 2010. can you recommend a van rental please that will pick us up at the airport, bring us to the terracotta warriors, then bring us back to the airport again for our flight to beijing. we don't want to take any tours. we just want a van to bring us to the warriors. i am assuming that the the total number of hours of this rental would be 8 to 10 hours?

also, is there a luggage storage facility in xian xianyang airport? if yes, does anyone know how much?

all your replies are greatly appreciated. thank you :)
