Thanks all for the input provided! Our daughter took classes and below are our impressions:
1st day - 1:
We show up to sign up Vivian for classes at Heavenly. Big surprise: they do not have a daycare, but 2 hours of classes in the morning and 2 in the afternoon. And these were to be the kid's first classes! We were both quite apprehensive when we'd learned how hard will Vivian's first day be, but we gave it a go because we knew that she is a fit kid.
Vivian rides the gondola and has a good class in bluebird weather. We did swing by in the afternoon 20 minutes before the class ended and she was still doing laps, in spite of the fact that she was visibly tired. These guys are running a good program, Vivian had fun and did get quite attached to her two instructors.
Daycare program at Squaw Valley with 1 hour of skiing in the morning and 1 in the afternoon. The operations here are a bit mass-production-like, but the daycare facilities are bright and well equipped. They take good care of the kids, but there seemed to be too many kids in the skiing class. They also have a 4 hours of skiing/day program.
We meant to go to Alpine Meadows that day, but did not sign up Vivian for classes the day before. We'd stopped by the kids' club at 8:20 a.m. and had learned that the sign-ups start at 9 (vs. 8:30 a.m. at Squaw Valley). My wife did check out the facilities and they were quite dark, so we'd ended up going to Squaw Valley instead for 1/2 day. We did the daycare program again, for 1/2 day.
Thanks again, eugen
