you can use the 484 exit in Belleview for access. 75 south,, Exit onto 484 and turn left at the light,,, go under 75,, follow 484 and turn right onto 475 south. Should be your 2nd light. If you live in the Marion County side of The Villages, follow 475 south till you get to CR-42.. Turn left there and follow 42 past 301,, the next light will be Buena Vista, Turn right there and that is the Marion County side.
If you live South of 466.... stay on 475 south it will make a sweeping left curve and turns into CR-466. Follow that and you will cross over 301. From there you have access to all The Villages. You can turn Right on Buena Vista or go all the way to Morse and turn right.
