They don't seem to like being disturbed much, and seem to survive quite happily on benevolent neglect. I dust the leaves, don't let them dry out, but don't let them sit in water (mine are in orchid compost which honestly seems to just be chunks of bark) and have them in a relatively shady window (and trust me, over here, the skies are mostly lightly overcast, so there's not a lot of light ) and they seem to happily occasionally grow a new leaf, but regularly put up flower spikes. It doesn't happen quickly, just in their own sweet time. I have two in bloom just now, each with two spikes of at least eight flowers (one has twelve, and is still budding out from the tip).
With orchids I think the best advice is "Patience"
