I rode this past summer, three things i took away:
1. Falls dont hurt as long as you have long sleeves (which are required)
2. Snowflex is extremely weird at first, but after about 15 minutes riding it youre used to it.
3. All the rails are a tad sticky because its warm, but the jumps are really nice and can be sent really deep with no issues.
as far as rates apply, i dont even know because i got lucky, i went on a family fun day, which skiiing is 1 buck an hour. i know they charge by hour, you would have to check website.
and the rope tow is a pain in the butt. but definitley worth it
