Sounds like there is a lot of politics going on with kashrus on Orlando right now. No, I have zero inside info. I'm just saying this based on other things that I have seen on this forum lately about restaurants changing hechsherim. And now you mention this guy who knowingly hangs up an expired cert.
Basically, these places in MCO have ten days where they may make literally a third of their profit for a year. They need frum tourists to survive.
I have no advice other than to say clarify which place(s) you are willing to eat at BEFORE you head out on your excursions. It's no fun to try to figure out if you're eating kosher while standing in a parking lot and doing research on an iphone.
