It's two across..You MAY be able to fit one adult and 2 small children, but you're not going to be able to fit the 4 of you in one row. But how about you and your youngest in one row and your two oldest in the row in back of you (or in front of you)? I do think that this would work out fine.. The only questionably "scary" part is the drop, and that's over in 2 seconds.
I wouldn't miss this if any way possible, but you are the one who knows your kids....
