Yes as in you turn up drunk you are not getting in, you try and smuggle in something you aren't supposed to have, you aren't getting in etc. Disney letting you book your trip and then saying you arent getting in even though you have travelled, paid a ton, have valid tix is wrong. I'm wondering how many people have rebooked before Disney have said even if you have made this park reservation there is a possibility you won't get in. I am probably reading too much into it as I have faith that Disney wouldn't do that to people.
