I know this question has been asked before,but is there any way of knowing how much is left on a pass,for instance if I have a 6 day park hopper plus 3 and i don't use it all, is there a number i can call to find out what i have left,or is it just hit or miss,this can be a decent savings when buying tickets,any help or info ,I have tickets fronm four different trips and need to know how much is left before i purchase again thank you
