I am new to this process and new to San Francisco and would greatly appreciate advice for a bidding strategy: I am going to a conference (so I know it is a busy time) at the Moscone Center in SF from 10/22 to 10/26, but will be traveling alone, so the hotel needs to be in a safe area. I am looking for a 4* hotel.....how do suggest I start in terms of price and region for that time period? Thanks so much, sgarg
