My DH loves to fish and has done the Disney fishing thing many times. It is expensive, but I figure we are on vacation and if that is the best part of trip for him, he works hard and deserves it.
Anyway, the price is for the boat, so you can bring up to 6 people. However, he always has gone alone with the guide and had a great time. The lakes are stocked with fairly large fish and I think in probably 8 or 10 trips, there was only one year when he did not catch anything. Usually catches many fish. It is catch and release.
I can't speak to the golf, although friends have told me that Disney has some of the most beautiful courses.
