Hi Charles - Vanda alliance plants very often offset from the base, and you can usually save the offsets if the main growth dies.
Some orchids just can't take drying out. This is definitely NOT one of those. It should dry out when it's cool.
Before getting one I read all about them here on Orchid Board. The main thing I noticed is they die quickly when they are cool and wet. I saw people writing over and over again that they let the moss get crispy dry through and through during the winter. Some of the experts here like Matt wrote of just
misting the exposed roots during cool weather, and not wetting the moss.
I bought the cheapest mutt seedling Neofinetia falcata I could find to learn on. I still don't think I'm ready for a more expensive one. I got mine from Hausermann's for $8. That sale is over but right now they have multi-growth blooming size plants for $18.
I have verified mine can live a long time with not enough water. It is in large chunk bark that dries out in about a day. Sometimes I am gone for a week, and mine gets no water, even when it's hot. Sometimes I work too much and don't water it enough for weeks at a time. It might get wrinkled leaves and root die-back, but it never looked close to dying. It didn't bloom this year, either, but I didn't lose any growths, and it's making more as we speak.
So I would suggest following the above suggestions. Repotting is to be sure you can see and remove all the dead growth. I personally would take it out of the moss right this instant, if you haven't, and leave it exposed and dry until it warms up tomorrow, when you can finish repotting. Based on my experience, I have a strong suspicion Neos can easily be grown bare-root with no medium, like more tropical Vandas.
