I have hosted dancers at my hotel, or traveled to the dancer's hotel, several times in many cities including dancers from Johnsons Ft Lauderdale.
I have never had any problem with safety, but I am ALWAYS let down by the personal interaction compared to what I received at the club.
Dancers are good at dancing, masseurs are good at massages, and escorts are good at fucking. I've never met one who is good at all 3, including at Johnsons.
