I've tried a few times with hibiscus and failed every time. They go into shock easily when they are moved from location to location, they need lots of water but have to dry out well between watering. Too much or too little light makes them drop leaves and they are more susceptible to spider mites than other plants. Having said all that I still try them once in a while because all my chams LOVE them, but I generally just buy a couple $10 plants and leave them in the cage until they are too far gone. I've given up trying to grow them at all, but here are some tips anyway.
Good soil drainage (aerated pot, pebbles on the bottom, mix of peat and soil)
Try to keep lighting/temps the same year round to avoid shock
Try to cover the soil to avoid it staying moist from constant misting. A cover or something that allows airflow, but keeps moisture out would be preferable.
These are the main things I've found. Let us know if you find something that works for you. Good luck!
