It depends on the severity of the crime. Thankfully, most offenses committed on vacation are low-level and simply result in a fine. A Panama City, Florida cop told me that he arrests over a hundred drunk, high, and rowdy people on Spring Break every year. He said that due to "limited jail space", most of these offenders are simply ordered to pay a fine, and spend only a few hours in jail. Because Florida has a "reciprocal agreement" with many other states, then if the person "fails to pay their fine" by the due date, then they risk having their driver's license revoked, and they could face additional fines. The person who is fined also has the right to "contest the fine" in a Panama City court, but most vacationers don't want to spend the time & money necessary to challenge the fine at a later date, so they simply pay it.
