The electric carts range depends on how many riders, how full a charge it has when you start (don't assume it is "fully" charged when you get it). With a fully charge cart, and two riders, you should be able to make it as far south as you want to go and then a few miles north and back with no problem. Our last trip, with 4 adults, two of them being hefty, we made it south, then up to the Palapa bar, where it fizzled. I might suggest if you are going north and south, go north first.
