I'm having the same debate (also flying to Orlando) I've seen all kinds of posts about people doing stuff like putting it in phones, etc. But, I'm kinda leary since if you've ever walked by the TSA area and seen the x-ray machines for carry-ons, it's pretty easy for them to tell if something ain't right! I've never seen dogs in domestic flight areas so I'm convinced carry-on is the way to go... but want to think of a good place to stash it.
Someone suggested disguising the weed in a pack of cigarettes - i.e. unroll the tobacco and load 'em with fine shake. This looks unsuspicious going through the x-ray in your purse or whatever. But you can't take much this way. Any thoughts/suggestions?
