Well I'm going to go out on a limb here and try to give you the best possible advice I can, but please realize that predicting conditions from one day to the next can be extremely difficult at Taos this time of year, let alone a few days out. Throughout most of March and April we see dramatic swings in weather. It can be 50 degrees and beautiful one day and it can snow the next. Here is what I can tell you with certainty:
We received some significant accumulation of great quality snow about a week ago. Since then it got warm and the powder we were skiing one day quickly turned into typical spring slush. Over the last few days, however, it has been considerably colder with a side of wind. The result is some firm snow. The groomers have been holding up OK but the off piste stuff is a bit dicey. That being said, I imagine you and your daughter will primarily be sticking to groomed terrain so this may not be that much of an issue for you.
Now here is where the uncertainty comes in:
There is snow in the forecast! But not much. A few inches can really transform Taos into a winter wonderland, but I can't guarantee that we are going to see any significant accumulation by the time you get here. If it stays cold and we don't get the snow they are calling for, conditions will most likely stay the same. If we get the snow, things could dramatically improve. Definitely keep your eye on the weather because ultimately that is what makes or breaks Taos.
Regarding Santa Fe, I've never been so I can't tell you if you might be better off going there.
And a final disclaimer, I'm currently in CO so my eye is on their weather. I hope this helps. I'm sure wherever you go you'll have a great time! Just go into the experience with a positive attitude and low expectations and you won't be disappointed (pretty much how you have to approach skiing in the southwest as we are in the midst of a terrible drought).
Give me a shout if you do make it into town (I'll be back on the 18th). I'd be happy to show you around or introduce you to some awesome instructors that could do the same.
