I am goin to South Beach in June and I was just wonderin what the chances were of me walkin in and getting a tattoo from one of the guys from the show. If there is no chance what are the chances of me just getting one there from someone else?

If you are willing to wait hours and then spend 400 bucks per hour, then you should be able to get inked by an artist at the shop. Don't count on getting inked by one of the "stars".

dc - scroll down a bit and find a thread called something like "My experience at Miami Ink". Somebody else did exactly what you're planning, and they told all about it.
