Absolutely no worries, you only have to ask at the place where you are renting the aircraft from and you will find pilots falling over each other to be your safety pilot for free. In any eventyou will have a 1hour check out with an instructor as a minimum requirement and they won't set you loose if they think you are not safe.
Florida is a good choice for starters because the ATC is more relaxed there plus there is no high terrain and apart from thunderstorms and a little turbulence when it's hot no big problems.
One thing's for sure, you will enjoy the flying. Beware paying up front as always!
