ticket

I am planning my first trip out to Tahoe and I want to give an estimate to people about lift ticket pricing. I have several questions: Is it cheaper to buy lift tickets early? What are the best deals on tickets? What can I expect to pay on average per day? I figured I'd keep the question...

ok so im heading over to park city in 2days.. but we're in a tight money situation... im 15 years old i look maybe 13 or 14.. but my friend looks like he's 10.. do you think we could get away with buying juniors tickets? we're in a tight situation any help would be welcome.. thanks!
