What should be protected from low temps?

Tommy, I left most of my orchids out until the beginning of October, the night temps were low 40s and daytime temps were in the low 60s. I have many Catts and Vandas and none were damaged. I think for short periods most of your plants will be fine. I would just protect from cold wind, cold rain and freezing (I know you said Miami doesn't freeze, but who knows with this year's crazy weather).
