If you try to book a hotel room in San Diego in September, you can probably get one for around $200-300 a night. If you try to do the same in mid-July during Comic-Con? You'll likely have to cough up close to $1,000 a night, and that's if you can get a room at all. If you're an Airbnb host, it'd behoove you to know about these sorts of surges in demand, so you can price your room appropriately. Today, Airbnb has rolled out a tool called Price Tips that lets you do just that. It utilizes Airbnb's own machine learning tool called Aerosolve that'll suggest room pricing based on the demand for rooms, its location, travel trends, the listing type and so forth.
