Having just gotten back, we did not find it necessary at all to use a golf cart. It actually felt good to walk off that buffet meal at Trails End. Granted, we were in the 300 loop and could easily walk there but with the buses running so frequently, it really is not necessary at all no matter where you are.
If you're looking for the fun of it, it definitely looked like fun but we had just as much fun getting around on our bikes and we still got the excercise out of that too.
I can see why disney had alot of availability the last couple weeks with those prices.
While on the subject, i think people are starting to push the limit as to exactly what a golf cart IS. there was a guy in our loop and i'm telling you, this vehicle was not a cart, it was more like a mini-jeep. i saw two very similar and they looked like they would tip very easily, very high compared to a golf cart. They also went much faster than a golf cart, didn't appear to be electric either. I just hope disney doesn't start restricting people bringing their own transportation because of this.
