If you remove your park hopper feature pay attention to what they want to refund you.
For my 10-day tickets I paid $85/pp for park hopping feature.
They wanted to refund me $92 for THREE tickets.
When I pressed they said that the per-day cost of my April tickets was substantially less than the new August dates. They become date-based when you remove the hopper. My refund reflected that difference. I politely told them that I expected to be refunded the full $85/op and if they couldn’t do anything about that then I would need to escalate to a supervisor.
I spent another 40 mins on hold but the supervisor fixed it.
Be aware of what you should be getting. And don’t let them give you less.
