Take note that this is a one-day stay on *New Year's Eve.* Two weeks ago, there were 4-star hotels were under $150 on Hotwire, but not anymore! So, I went to Priceline and got this just in time before everything filled up. Bidding strategy (please tell me if I could've done it better): $100 for 4-star and up at Union Sq East $105 for 3 1/2 star and up at Union Sq East $105 for 3 1/2 star and up at Union Sq East, Union Sq West/Nob Hill $110 for 3 1/2 star and up at Union Sq East, Union Sq West/Nob Hill, SOMA $115 for 3 1/2 star and up at Union Sq East, Union Sq West/Nob Hill, SOMA, Financial/Embarcadero -- BINGO
