I was just down TV for a visit and purchased a map, ($5), from the Sales & Information Office in Lake Sumter that included golf cart trails that was a better quality, (magazine type paper), than the one given out for free by the AAA.
If you plan on studying the map, order one through the Sales Office. I find it saves time to study the map so you can quickly find your way around TV without getting lost. Time is a precious commodity for your first visit as time will fly by.
There are some posts that have excellent suggestions for things you might want to do for your first visit.
Most of all, enjoy every minute of your planned visit.
