I want to book a room in San Francisco 4* 5/6-5/10 in USE or USW. We are 2 adults and 2 children (one age 5 other infant under 1). Most of these hotels appear to have only king and double/double rooms -- both of which are fine for us. Is there a big risk of trouble if we proceed with priceline rather than hotwire? Prices appear to be considerably less ($75-80 vs. $110) on priceline vs. hotwire.
