If you have 5 or more it's $10 off per person, and if you're staying at the aerie resort there's a further discount!
You can find Groupons that make it around $50 per person. Otherwise it's about $75 during the week and $85 on weekends b plus whatever you tip.
Group discount info here is incorrect, according to the site you need 8 for a discount and it's weekdays only
Worth every penny.
