I searched your blog via internet and I know you visited SF before. You mentioned that you used Priceline to book the hilton from around US$80 something per day, how can you do that? As I will visit SF in February, I want to know how can I check know which hotel will Priceline book for me? As they don't show the name, just the hotel star grading. Can you tell me more about how to use Priceline to bid the best deal. Thanks a lot!
