Melissa, I'll just throw this tidbit in...
About 6 years ago I was flown out to SFO to interview with a Chinese co. based in So. San Fran.
As most of us know, US hotels don't have a 13th floor. This company had a contract with the Holiday Inn/Burlingame and put me up there. Not only was I put on the 13th floor, my room number was 1313! I was told later that to Chinese people the number 13 is considered lucky.
BTW, I turned down the job offer, though it was tempting to live in the Bay area.
