Haven't been to the parks in 5 years! I have 2 (6 day park hopper) wdw passes currently parked in my account. Would they let me divide them into 3 day park hopper passes?
No you can’t do that. Depending on how old your tickets are, you may have 14 days from first day of usage to use them up, or if you have date-based tickets you will have less time to use them.
