hurricane harbor: I'm going to Six Flags Great Adventure next week with my friend and my sister wants to go to the water park with her friend. Can you buy Hurricane Harbor and the theme park tickets at the same gate? Or is there a completely separate entrance for the water park that you drive to? So basically what I'm asking is, can you get to the water park from the main theme park or do you have to drive to another entrance for the water park? Thanks.|||They're separate parks. After going on the road to enter six flags there will be a parking lot for hurricane harbor, the safari thing, and the parking lot for great adventure is further on the road than those things. There's separate entrances for each park, and if you don't want to walk really far you have to drive and park in the separate parking lots.|||there separate parks. admission is not joined together. u have to pay separately.|||you could just buy them in advance online...
