Cozumel had hordes of tourists before Playa del Carmen had a single one.

Target group should be tourists via AirBNB rental or westerners who want a top historic apartment in the old city to experience the true Tbilisi style for mid term rents (like 1 year or so as posted employees).If you rent via AirBNB, there is an agency, we host ge. https://www.wehost.ge/en/home/They will rent your apartment for 25% fee, which is very reasonable, considering this includes advertisement of apartment, cleaning, 24/7 availability for tenants, etc.

We are a suburb with not many tourist spots or shops etc.

The Technical Directorate will conduct the technical and legal evaluation of the projects and is responsible for recommending to the Council the exemptions specific to each request it evaluates.A Classification, whether Provisional or Definitive, is nothing more than the approval by the Tourism Development Council (CONFOTUR) of a given tourism project, as capable of benefiting from the benefits and incentives of the Law.Likewise, with the approval of resolution 49-2014, a step is taken for tourism projects that may be included under Law 158-01 and its modifications, to offer health services, and that can generate important tourist flows, under medical tourism marketing channels, not common to vacation tourism.In short, all exemptions granted by CONFOTUR are established in Law 158-01 and its modifications.

I was looking in the Fernandina Beach area as it is a tourist area.

St Augustine is year-round and a top-tourist location and as long as you pay your STR taxes it's friendly.

Is the area steady for tourism or expecting to lose tourist going forward?

It is a tourist town with both skiing/winter sports and summer hiking/water sports.

In Idaho Falls, I didn't expect it to be a strong STR market since it isn't really a tourist area, but there was one literally right across the street from me and I was able to see it stay rented year round.
