I grow all my Vandas in glass vases, humidity in the house is about 40%.
I've not had a failure growing them this way, I water them twice a week all year long and spritz the roots the other days in summer as well as watering.
Feeding is done every two weeks in summer. When it's hot (above 25C here, not that often) I leave about 1cm of water in the vase which has usually evaporated by the following day.
"Repotting" is also very easy, just get a bigger vase and put it in
With a vase you can easily modulate conditions as you can see what is going on and there is no media that can stay wet, it may be that in your warmer conditions you would have to water more frequently.
