Interesting. I had no idea some rest-stops had manned security. Heck I went through a town the other day and stopped at a Bank of America branch, and there was a security guard on duty there as well. First time I've seen a security guard at a bank.
Security and self defense is really up to the RV'er etc. We always carry a great security crew of 5 well known very loud speaking dudes. Mr Smith and his buddy Mr Wesson, Mr Colt, Mr Ruger, and Mr Hi-Standard. So far in our 49 years of extensive RVing, we haven't needed any of them to raise their voices once yet when in they are in the RV. Fortunately for us, they work very cheap, don't really eat anything but sure enjoy an occasional light oil massage rubdown, never asked to use the potty once yet, and always stay out of sight but are surely ready to report for active duty instantly if ever wanted. They do seem to really like us taking them out for fresh air and exercise and working their joints and voices at least once a year and we are delighted to keep them very happy.

We need to get back to the topic. However, be sure you know where you can legally carry and how to legally carry.
[info mode on]Just a short eduction about this in case you are transiting Florida. Stand you ground will not protect you if you do not use it correctly. Some people think, quite incorrectly, you can pursue or follow someone and still use SYG.
SYG was intended to be used when you are in transit, or somewhere you are lawfully allowed to be. SYG was also intended to prevent prosecution both criminally and civilly of an otherwise innocent citizen. In some states, a person defending themselves could be prosecuted in either or both venues if they did not retreat if there were any way for retreat.
In self defense situation, for the civilian as opposed to law officers, you must reasonably be in fear of your life or grevious injury.
As far as the law is concerned, once you follow/pursue someone that is not an act of fear. The implies if you were truly fearful, you would be going some other direction away from the alleged thug(s). So at this point the police and the prosecuting attorneys is going to have to examine the case much more closely.
Mostly, what you have to do is avoid situations. It will be far cheaper and less time consuming if you do. [info mode off]
I would expect in FL open more well lit and traveled rest areas the chances of problems are little remote.
