You cannot get a better deal than $12 for a whole day of skiing (weekday). This place has so many awesome deals.
As a native Californian (grew up skiing in Tahoe), the runs feel terribly short, but I don't think you'll do better here in Wisconsin.
There were no lines to speak of, everyone was nice, the conditions were near perfect. Lodge isn't huge, but had everything I needed and was very clean and accessible.
Kids 5 and under ski free (doesn't required paid parent ticket), and parents can teach them for free (if you're in street boots), so if you buy rather than rent, you're basically teaching them for free, which is amazing.
Can't wait to go back!
