Can you wait until arrival to buy tickets and get the FP+ feature at the kiosk on yourfirst park day? I will be staying at the Dolphin on a last min. trip and haven't had any experience with FP+. Does it have to be linked to an armband, or a ticket? And can you still do it the old way and get regular FP? I'm so confused. Already way past the 60 day window and I'm worried we won't get anything done.
