Prices vary by date(on 2/19/18 the day rate was $134 for adults and kids aren't much less) but somewhere around $725
Plan on being broke for a week and eating cup noodles
Parking is $20 and as already answered you should check website for current rates on the date you plan on visiting. Daily rate decreases when you buy multi day passes. Also if you are a AAA MEMBER they also have discounts. You can save a ton of money also by packing sandwiches, fruit, snacks and water bottles
Prices just went up again, check their website
The cost varies by the amount of visitors to the park. Obviously you pay more when the park is crowded and Less when it is not. I'm not sure how that works, you can check out all of this on their online site. Don't forget about parking It's expensive!
