Need all the help I get from all the experts. We, couple 36/35 yrs , visiting SF for the 1st time for 4 days. Budget 100-140 USD + tax per night. Looking at Union Square area, between 25May to 29 May. Have pre booked 2 hotels - 2 star for all inclusive 115 USD and 3 star for 160 all inclusive in Union square. Was recommended to try pricewire to better it in terms of hotel quality. Need help how to go about bidding "name your own price" for 3.5 to 4 star in Union Sq ( east preferable)...with a max budget of 140 USD (ideally around 100 USD). Any tips /suggestion, whether this is realistic?
