We went to SF once before, it was in May a few years ago. We stayed at the Mosser for a good price ($85/night). We want to go again this year, staying either in Fisherman's Wharf or Union Square (NOT Tenderloin.) Everywhere we check now is super expensive - like a Best Western costing $300/night or The Wharf Inn for about the same. Can anyone tell me why that is? Is September their high season? Can anyone advise on a decent place to stay - thinking $150-175 at the most in either of the two above mentioned areas. Any suggestions would be welcome.
