Hotels are subject to considerably more regulation, which is not self imposed. Think public safety, ADA access, safe working conditions for employees, adequate parking, etc. Oh, and they pay more taxes and have to collect, report and submit all those damn tourism fees. Your attitude is off-putting. I'm going to suppose it came off different than what you intended, so that I don't scream at you.
Comply with the rules. Get a copy of the SF Convention schedule, add in the major activities like B2B (that means Bay to Breakers in SF, for those readers who live elsewhere), festivals and the like, then choose your days carefully. Less work, still great reward.
An alternative is to just get a roommate.
