I don't know the actual statistics, so I can't say for sure. From what I remember, it did hurt tourism but people quickly forgot about it. The fishing/shrimping industry locally took a major hit though as far as I know. Even not considering the moral/ethical responsibility to take care of the environment, it seems incredibly risky to the state's main form of income to not take it seriously.
The Governor's office would like you to know that tourism is record breaking, has never been better, and Florida is amazing.
