If you are an annual pass holder; is there any discounts, or specials, for visitors that want to go to the park on a two or three day pass. What's the cost?

We went as a guest of a passholder and got a 50% discount... in our case $54 instead of $108.

yes, there is a discount for your guests with an annual pass and 10% off some items in park with your annual pass. i don't remember the discounted price for getting ticket for friends and family. can check the website or call them.

Only for the passport holders

Not really, unless you buy a year pass
