a) Selling space in your house by the night this way most likely violates one or more state/local laws. First, you're probably not operating with a business license.
Second, most cities have specific "bed taxes" (often 10% or more) for hotels. This is a significant source of revenue for touristy cities. Some cities also have specific laws about vacation rental properties (some actually don't allow rentals for less than 30 days)–even though I doubt these arrangements would qualify as a vaca rental.

Bolt Bus can only (for the most part) be booked online and has free wifi. It also uses variable pricing based on demand (initial tickets usually are priced at $5 or less).

At least that's been my experience and my friends' experience as a frequent user of both.
