Anyone (successfully) growing orchids in the Florida Keys?

[JanS]

I know a good number of regular contributors to this forum are from Florida...but the mainland. My wife and I are very seriously considering buying a second home in the Florida Keys (Big Pine Key area), so I am wondering: could I transfer and maintain my sizable orchid collection there? I know the temperatures will be fine but is the air too salty? I have two options: 1) keep them in the walk-in modular greenhouse where they are now here in California which I would also transfer, and have somebody come and regularly water them when we are not there; 2) place them all outside and hope the rains are regular enough and pests are not a concern.
Any advice will be greatly appreciated!
