BIG like.
I also have a MI CCW. My wife and I visit Disney twice per year..... and for MANY reasons? I would never THINK of bringing a firearm there.
First? Disney does not like this.... and it's THEIR Park, not mine

.
Second? Disney does a very GOOD job of managing security. I really don't personally think that I could do BETTER. "Security" is tough.... it's somewhere between "shoot everyone: they MIGHT be a threat", and "Don't worry, be happy". A damn tough job. Disney MAY not be perfect - neither is homeland security. Balancing Safety, and a good Vacation is a VERY tough job.
Now - my PERSONAL outlook? It follows the oath that Doctors take: "Do no Harm". I would rather die than harm an innocent. And WDW has a LOT of innocents within the Parks - children.
Which brings up my LAST point: It's a nightmare scenario for a licensed Gun owner.... or a POLICE Officer.
Heavily crowded park. LOTS of Children running around. You have a legitimate issue, covered by Law. Shoot? Don't Shoot? What is just BEHIND the aggressor? Was there another way to address this?
Folks - our POLICE agonize over these issues EVERY DAY.... and it's their JOB. We have a CCW - great. HOW would you feel if you killed that little girl in a Cinderella outfit, just by "missing" ? How do you imagine a POLICE OFFICER would feel? This is a Golden Opportunity to let the POLICE do their job. Your best weapon is your CELLPHONE. Dial 911, and refuse to be "Batman".
Just me.... I would NOT want to be the person that killed a child at WDW, over a perceived problem, by missing my target. I'm 64, and if I get "hit"? Better ME than some wonderful 8 year old in a Cinderella outfit. All personal opinion.... and congrats to the Orange County Police that FACE these issues on a regular basis. This is a true nightmare job - and you handle it well.
RESPONSIBLE authorized firearm carriers just would not DO this sort of thing.
