I've had one for over a year now and bloomed it successfully by:
1 Keeping them moist all the time during growing season;
2 Not watering in the winter except for the occasional misting;
3 I have mine potted the trational way in sphag
For your month away in the winter it should do fine without watering or misting.
There are many experienced Neo growers on the forum here so there will be plenty of help coming soon
