What porn stars will be in Miami during those dates? If no big ones what about the amateur ones like on bangbros, realitykings, etc..

Where are all the bangbros and reality king girls?! They film in Mia/Ft Lauderale... they should be all over down here right?

Check out their website and reach out.  However filming for several movies only takes a day or two so chances are pretty slim that you'll catch them.  
Also Keep an eye on the ad board lots of unknown starletts (or newbies) can be found there.
But I would go with the recommended Adriane Deville, but from what I understand she books fast and way ahead of time. So I would not wait any longer!
