My family owns the membership passes. My other in law bought our family season passes. Because I didn't cancel our memberships with 45 days of the bill cycle, I am charged 2 more times on my membership. Reached out to Six flags about on my problem with technically being double charged and they said they will not due anything about this matter.
If you plan on making a purchase for a friend or family member like they recommend, I suggest reconsidering.
