flights from Havana to Cayo Largo del Sur

[worldtraveller]

Dear Forum,

We are thinking of visiting Cayo Largo del Sur in December 2023. We cannot figure out which airlines flies from Havana to Cayo Largo del Sur airport.

Also any good advise on 4/5 stars adults only hotels, and clothing optional beaches would be great please. Thank you

Is easy to rent a car to reach nice beaches?

Sorry for all these questions but it is all new for us.

Much appreciated.

Regards
