The Miami/Ft. Lauderdale area has the most number of outcall agencies, similar to Canada.
There are quite a few Canadian SPs who happen to work for these agencies. Since it's Florida, you'll also see quite a few chicas from Cuba, Latin, and South America working for these agencies too.
So far, LE has ignored most of the Miami agencies, but who knows. In addition to LE risk, rates can be 50-100% more than what you'd pay in Canada, with higher likelihood of B&S.
If I were you, I would skip it. Go for Disney World, the beaches, civilian chicks, the warm weather, but I would forget the hobbying.
