If it is gold yes
No you don't need to buy it
Depends on the season pass that you bought. Some cover only one or the other water park and others cover both. If you login to your profile online through the six flags website, you can see if it covers both or call the customer service number. They'll tell you
Depends if it covers both parks
You have to have one for hurricane harbor
The Magic Mountain season pass should also work for Hurricane Harbor.
