voting and driver license issues with full time

I would verify if under Florida law that would qualify as a legal domicile address address before you jump into it. After that, you'll change all of your DL, legal documents, financial, etc to that as your permanent address. Depending on FL voting laws, you may have an issue having absentee ballots sent there, but the registrar can tell you. We have voted absentee "in" TX for 5 years with no issue using Escapees as our mail service. Good luck.
