Even if you don't get a good chance to go orienteering, getting used to the way contour maps work is probably helpful, especially if you can look at a map immediately and know what a feature looks like, rather than trying to work it out in your head. This site is pretty cool:

You can download either aerial photos or contour topo maps from this site. I suggest you look up a few contour maps of famous places that are slightly more hilly than Florida. I also recently got a bit of mapping software (DeLorme Topo USA 4.0) that could be helpful, although it's a little bit pricy. The program gives you side-by-side two-dimensional topographic (contour) maps with three-dimensional angled images of the land features (with contours printed on them), so it's a pretty good way to get a sense of how contour lines translate to geographic features. It's pretty addictive if you're a map geek like I am.
Here's the site for the mapping software:
