Hi Andre, I'm in Florida too, and it sounds like my climate is fairly similar to yours, a minimum of about 45deg. F (6deg. C) very rarely in the winters here. Hot and muggy 30 to 35deg. C in summer, with a sea breeze and heavy rains in June through September.
My Vanilla Orchid is currently growing in a basket hanging up in my pool cage. It has orchid bark and some sphagnum moss as medium. It gets full sun through the screening of the cage (about 20% shading at most) for most of the day in summer. It gets a generous misting every morning through the summer months, and a light misting in winter as well. There's no such thing as too much water or humidity for these, I think.
In winter it will be moved to a larger pot and grow on a tall totem of tree fern (I had a tree fern in my garden that mysteriously died). For the cold weather, it will live in my 'hoop house' which is on the south-facing sunny side of our garage, protected by frost cloth on the coldest nights. The hoop house has all my warmth-loving divas in it, never goes below about 12 deg. C at night plus is protected from the cold northerly winds that arrive after a weather front passes through.
There's also a very large and lusty Vanilla Orchid growing as a permanent display in the huge greenhouse at our local botanical gardens. It is planted in the (sandy) ground with bark and amendments and grows throughout the rafters of the greenhouse, 20ft. up and across in some places. It gets lots of sunlight up there, year round. They have actually succeeded in growing vanilla beans on this huge plant there, with careful attention to hand-pollination of the beautiful, fleeting flowers.
