So here’s some warnings, just before you get all excited.
In your case to be able to see what was available in another park, you would have to go through the Modify screens, past the warnings about FPs getting cancelled.
Having done that and seen reasonable FPs, you’d then need to come right out of the Modify screens. Otherwise it would delete EE and Dinosaur.
So then you go to the Dinosaur FO and cancel it.
Now back to Adda new FP and through the rigmarole.
Not for the faint-hearted. You’d need your wits about you. Way too easy to mess it up in my book
I wouldn’t plan to be doing this unless I was genuinely relaxed about what rides to do in the next park. Then I’d just cancel and only then worry about what’s available in the next park.
Add to that the fact that MDE can glitch. If an FP doesn’t drop off your MDE when you scan in, then you won’t be able to continue without a visit to GS.
