Cars work just fine - they get you everywhere you'll need to go..........except for out on the golf course.
Otherwise, it's a bit of a cultural thing. Golf carts are fun, a unique form of transportation, pretty inexpensive to operate, easy to find a parking space at the squares........pick your own reasons.
As far as distance driving goes, a gas cart will go around 200+ miles on a fill-up. Electric carts can get you pretty much anywhere you need to go during a day before recharging at night. The size of TV isn't really too much of an issue for most people.
But you've gotta do what you feel comfortable doing!
