We were at GT last week. At check-in in Port Canaveral the agent asked if we were vaccinated (we are) but said she didn't need to see the card, she just had to ask. She never asked one single other health question, like whether we'd been sick recently, whether we'd been around anyone sick, etc. Nothing. I was really surprised. Then onboard, there was nothing to indicate that you couldn't get off in GT if you weren't vaccinated. No announcement, nothing on the app.
