Of course they are not a necessity, they are a luxury or least a convenience. You can get around perfectly fine without one by using the internal bus system at FW, but God forbid, you might have to wait 2 or 3 minutes at a bus stop. Although there may be more campsites now, Fort Wilderness is no bigger now than it used to be. But of course using a cart is more fun than riding the buses. It's up to you to decide if its worth it. if its worth it. Rental is now approaching $60.00 per day.
You can park carts at near the boat docks at the lake. You cannot drive them to the TTC. You have to bus to get over there.
