This shouldn’t come as any great surprise, given the infamous pricing in the City by the Bay: San Francisco ranks as the most expensive place for business travelers in the United States according to a report from Business Travel News. The report measured the prices paid by business travelers in the 100 biggest American cities. Business travelers spend an average of $547 per day in San Francisco, the report reads. California cities in general were expensive: Santa Barbara, No. 6, at $409; Los Angeles, No. 8, at $402; San Diego, No. 23, at $348; and Anaheim, No. 35, at $319. One surprise in the report was Detroit showed the fastest increase in hotel rates, a 22.5 percent jump from 2014 to 2015. Detroit’s average nightly hotel rate of $198 is much lower than San Francisco’s, though, which runs about $370 per night. Despite its high prices, San Francisco reported a record 24.6 million visitors last year, an increase of 2.7 percent over 2014; clearly, the high prices aren’t keeping any travelers, much less business travelers, from frequenting the city.
