Just wanted to contribute my experience from today, Saturday 3/7:
We started at Fantasia. Got there around noon. Was told one course had a 40-min wait, and the other had a 50-min wait. (I didn't know about being able to book tee times in advance.)
We didn't want to wait, so we drove over to the Blizzard Beach courses. (BTW, Blizzard Beach was closed today, even thought the temp was about 65--not ideal waterpark temperature, but far from frigid. However, the mini golf was still open.) Note that parking there is very limited; we got the last spot in the lot (though it cleared out by the time we left). There is additional parking at Blizzard Beach, but that's a pretty good walk.
Wintertime course had a 5-minute wait; summertime had none, so we played summer. I thought the course was OK. Nice theme, very fast greens. Only reason we did it was because we had the park hopper plus, and it was no additional charge to us. I think paying $14 or whatever regular price is is way overpriced. (Then again, I suppose there are lots of other places in Disney to spend money faster.) Worth a quick visit if you're looking for a break from the parks or an arrival/departure day but not worth going out of your way (or paying full price) for, in my opinion.
