There are members of our orchid society who have great results with full water culture, so it should work for you, too.
You already live in a high-humidity state. Misting of leaves is a bad idea for most orchids. It keeps the leaves wet longer, so fungus can enter. A humidifier is a better way to raise the ambient humidity, but I'm pretty sure you don't need one. Phals do fine indoors in much lower-humidity areas than you. "Humidity trays" are not effective in raising humidity, but they are good for keeping water off furniture.
It would also be funny to watch you go into a Florida hardware store and ask to buy a humidifier.
