I have three vacation rentals in the Smoky Mountains of Tennessee, all of which perform well year-round, and the area is very well-established as a tourist destination.  

Is the area popular with tourists? 

Wrigley can have low vacancy rates as it's a tourist area.

For example, I live in a tourist area where several couples or 2-3 families will try to meet for a larger vacation.

has become an extremely popular tourist trap over the last decade of so. 

I furnish lots of tourist info, maps and coupons for local businesses.

Would it be viable as an air BnB eco-tourist rental?

I live in a small tourist town and the ONLY name you'll hear is Airbnb - it's become synonymous to saying "Google" when you mean search engine.

I'm skeptical of AirBnB guest checking into your place cause it's far from any tourist attractions.

Then, the issue has already been addressed by the state/county/city, I know what the deal is, and it's unlikely to change (or at least change dramatically) - the gov't is already getting their cut so they aren't likely to mess with a good thing.It seems that urban areas are the riskier ones from a regulation standpoint, but from a cash-flow perspective they can be more reliable because of the variety of travelers they cater to, not just tourists.
