You could do this:

Launch your park. Then, go to GC and sign out. Relaunch your park and it will start a new version "locally". Play one or two plays and close the app completely. Log back into GC and re-launch your park. It will ask if you want to restore the local or GC one. Choose local. That's your new primary park.

For the other three, if they are the only thing used in a "made up" GC account, sign into GC and have someone you trust change the password to something useless. After that, sing out of Game Center. Then you can never sign back in to "visit" because you won't know your password.
