Everyone has good posts on this. We have a place in the North because we prefer to stay there. However we spend a lot of time in the South because there is more to do. If you are the type that likes to stay out later and bar hop, I suggest the South. You can do that a bit in the North but its very low key.
If you visit during the rainy season you will likely have a tougher time commuting your your cart to/from the North.
Enjoy!
