Where to go for the end of the summer trip?!?

so im a freshman in highschool aand i planned a start of the summer trip for 27 kids! we went down the shore to ortley beach and then went to the seaside boardwalk. now im trying to think of a place for us to go next. people have said go dts again, go to mountain creek, go to six flags. but im nervous cus some people dont like rides and i kinda want us all to hang somewhat together and i feel we would split up! it will also be hard to plan those things because u have to buy so many tickets and parents wont really wna drive. do you have any ideas on where to go or what to do?!
