Hi - wondering if anyone knows the answer to this: I am looking to buy annual passes using the promo deal. We plan to activate in June 2018. My son will turn 10 in Jan 2019 and we will want to use the same pass again in May 2019.. so my question is what happens when he turns 10? Can he still use the same 3-9 child pass or will I have to update it to an "adult" pass at that time? Any if so, will I lose the promotional discount at that time since the promo will be over? thanks!
