Florida resident rates are for Florida residents. You can take your chances and hope they don't ask for your ID, but in many cases they will. And if they do, and you aren't from Florida, you will have to go to Guest Relations and upgrade your ticket. This can be time consuming especially when just getting to the park.
So really it's up to you how much the difference is and how much frustration you may or may not want to have to put with if they check your ID and there is a long line at GR in the morning.
That's what i figured, just wanted to verify before buying. Thanks Robb!
