So the problem is that's what you are talking about, but not what I'm talking about.
No, you can't get into a park without a reservation, even with a ticket. But unless park is sold out - which may be the case more often with Disneyland - you can make a reservation that morning, right?
I'm saying if you have a park reservation already, you can change the reservation day of as long as other parks have availability - and obviously if you didn't already tap in at the previously reserved park.
I thought you were saying you can't do that anymore. And we've done it before, so that's why I thought maybe AP holders didn't have that capability.
And my original post about this was expressing how -for us - it's basically the same as having to make fast pass +. Both systems had us tied to a park. But in my eyes, fast pass + was more difficult to change parks day of because you lost the fast pass and a lot of time ones at the other park weren't available! At least that doesn't happen when changing a park reservation day of.
misunderstanding.
(now today for example would NOT be a good day to be spontaneous. Looks like some parks are at capacity for next couple weeks, most likely due to Spring Break)
