For the 6 and 8 and the 2 zip lines should be good enough. The $49 package should be good for there ages.
The 7 zipline course has a min age of 8 yrs old. So, for a course that your whole family can do, you should choose either the 2 zipline option or the 5 zipline option. Hope that helps. We look forward to hosting your family.
