We have only been to FW twice. We have had golf carts both times and enjoyed them. (Rented from Kenny). The kids had a blast with them(yes they have a drivers license) ,Running to get soda, going to the fireworks at the beach, looping ect, the pool. The last trip this past spring we had the carts for 8 out of the 11 day trip. Yes the bus is not as convenient but it's not that big a deal. We stayed in the 1200 loop and the walk from the boat wasn't very long at all.
Cheers,
Ed
