Trip in USA

first, i am a person who has to take EVA air, or i would rather stay in taiwan. so i get the ticket from taipei to san francisco of the EVA airline company. i will arrive san francisco at 3 A.M. in Sep 3rd, and the tickets cost me about 31,650 NT dollars. and i got a rental car with taxes and fees added for 113.74 US dollars (http://travel.travelocity.com/car/CarDetails.do?ln_num=1&threadNumber=&SEQ=387865869)near the airport to pick me up, it is going to be Hyundai Accent ecnomical type and arrive the airport at 4 A.M., which means i have to wait in the airport for 1 hour. during the time, i may try to hang out in the airport and shop something in some stores as well. in the first 3 days, i rent a hotel called Motel 6 Monterey(http://www.orbitz.com/App/ViewHotelDetails?z=2abw&r=4c&lastPage=interstitial). it costs me 49.99 US dollars each day for a room with 2 guests. and as to the other trip to Tahoe, i am going to stay here for 3 days, so i rent a place to live called Caesars Tahoe(http://www.expedia.com/pub/agent.dll?qscr=dspv&flag=l&itid=&itdx=&itty=&from=f&foop=0&hwrq=&htid=22902&spsh=&spsi=&crti=4&nfla=1), and i have to spend 93.00 US dollars for each day's rent. then, however, i need to drop-off the car in the same airport in san francisco. and i am going to leave from that place, so i have chosen the details when i rent the car.
