I haven't yet played mini-golf at WDW, so I can't say if they're better or worse than the other area mini-golf places. But my wife and I love playing at Pirate's Island in Kissimmee on 192 next door to Walmart and Medeival Times. We have also played at Congo River Golf, which we enjoyed. Then there is that Hawaiin Volcano themed one that looks pretty cool, although we have never played there, as well as the Pirates Cove one, which we have never done yet. However, I was thinking I read that there is one right on Disney Property somewhere, which I would like to try this next time.
Speaking of mini-golf, which one of the Disney ones is supposed to be the easier of the two? I remember reading that one of them is very hard to play on.
