I have an old non-expiration pass with a couple of days left. Will I still be able to get into the parks through the turnstiles or have the turnstiles all been replaced with RFID scanners?
More and more I expect people will be "encouraged" to trade in the old tickets for RFID cards...
There were still a couple of old turnstiles at MK to the far left behind the "Imagineeers" wall where they were converting more of them a couple weeks ago. Not sure when the last of them will be converted.
While the majority of scanners have or will be converted, paper tickets will still be accepted without issue. There are handheld scanners for just this purpose. You will have no issue.
We did see that there can be a delay in admission as they don't have the hand scanners at every entry point, so you might need to wait a bit longer. But you WILL get in.
I would go to guest services with them and get new tickets issued. They shouldn't charge you for them as they are only converting the old tickets to an RFID one.
