> That said, AirBnB's site shows the total cost for a stay when browsing
This depends on which site you’re browsing on. I don’t think US does this, but you can browse the AU or Canada version and set your price in $USD because those geographic “editions” have to post the all-in cost up-front.
Yes, and I think the only exception might be California where it is now required that prices include previously hidden fees such as "resort fees" (and "landing fees", etc for airlines).
