How do I change my park Reservations?

I made reservations for my park days in September, but now I would like to change a few of them. How do I do this?
Thanks for your help

Just cancel what you have. Then you can rebook something new. There’s no modify option. This is the (only) way.


Yes what OBNurse said. But I’d like to add…, check the availability calendar for openings to the park you want to change to. Make sure there are openings before you cancel existing ones.

I hate that there is no modify option… I’m always afraid that in the space between when i cancel my existing one and book my new one, it will disappear!!!
