Honestly im from the east coast so anything is better than what we ride here. Kind of sucks that they arent getting any snow and the trip is booked. Honestly we love riding glades all day and some park. A nice day with some pow and backcountry is all we are looking for, hopefully the weather turns around and we get some nice days.
Some other members may be able to give you more advice on Glades as I haven't really ventured into that type of riding yet. I would say if you want to ride park one day, stick with Breck or Keystone, and on the days you want to ride anything else, head to BC or Vail.
As for conditions and snow, I would take a look at this website:
The Colorado Daily Snow | OpenSnow
Hes about the best forecaster I've seen for snow in Colorado so far. Looks like its going to be dry till around the last week of January and then it may turn around.
