I've played at the Fantasia Gardens course. They have two courses there--one is called the Gardens course, I can't remember the name of the second course. The Gardens course is very easy and whimsical with characters from Fantasia. The other course is a lot more challenging (I've never played that course).
If you are using Disney transportation, take a bus to the Swan. Walk into the main door and walk straight through to the back door. You will be between the Swan and the Dolphin. Take a left, and cross the street. Fantasia Gardens is right there on the left. It's only about a five or seven minute walk.
I've never played Winter Summerland. I imagine that you could probably get there by taking the bus to Blizzard Beach, and walking from there.
