Yes you can buy there or online. It's cheaper parking if you get online I believe.
Yes you can buy tickets at the park
I bought my tickets an parking pass at the hotel i stayed at but yes u can get them either way
The parking is the same. If you buy the tickets in advance (i believe it must be 48hrs) you'll save about $25 per ticket. You can also bring a specially mark coke can with you to receive $20 off your ticket. Normal ticket at the park is about $82 after taxes
