Kylee is right. SF has a much broader range of quality/pricepoint in hotels within walking distance of the conference than just about any other major conference city. Cheap hotels are *much* easier to find than in, say, Seattle.
OP either likes hearing the sound of his own whiny voice or didn't bother to spend three minutes on a hotel website.
Ever been to Chicago? See, the conference's second conference is held in the second city. Where there are effectively limitless options within a brief walk of the Loop. Some really cheap options that involve things like scared bathrooms, and some moderately priced options are are 4 star hotels, including all the amenities one could want, and that allow one a wonderful <15 minute walk across the river and to the Palmer House.
And also allow one a <15 minute L ride to neighborhoods with actual character and people, rather than techbros.
f**k SF. May we never go to another conference in that once-cool, now-worthless city.
