I can't help you with the fishing location aspect, but maybe on the traveling part.
They may take away hooks and lures on carry on, and will definitely take away pliers, scissors, etc. I'd throw the reels in your carry ons, and throw a small selection of lures and hooks in a box in you checked bag. Shouldn't weigh more than half a pound.
Your rod idea is probably the best option. But depending on the rods you were planning to buy and leave there, it may be more cost effective to just ship some 2 piece rods down to where you're staying in a long rectangular box. Then ship them back up when you leave. Again, if you were going to buy really cheap ones, then buying them there and leaving them might be better.
What species are you looking for? Bass, or something saltwater?
Also, what team are you a a coach on? Most little league teams don't have spring training in Florida, so possibly a higher level team?
