Kingianum can be kept lower than the temperature range you mentioned and the flowering will be better. Keep it on the dry side as it can easily sprout keikis depending on the type, but not bone dry. Aim for enough watering to keep the pbs plump.
Nobile types are my favorite.
Also, depending on the hybrid, the temperature range you mentioned is fine, but if you want to make sure you have great flowering, then even 65 is rather too warm. I recommend keeping it under 60 to be safe (this is night time low).
You do not want to hold water until canes shrivels. It is actually bad for the plant.
You want to keep it plump. When you see slight wrinkles, you can water it, but you don't have to wait. You can go by pot weight and when it is completely dry (the pot will feel very light as compared to when it was just watered thoroughly).
Also, you want to give them lots of light. This also helps ample flowering.
Phal type dens may be perfectly fine in that temperature as long as day time temperature is significantly higher and the roots are kept on the dry side. Do they have more of round shaped flowers??
They have more of biggibum in them and take "cooler" temperature better than others. but to be safe and if you can, keep them in the warm room.
Good luck!
