I actually took up golf so I could play with my Dad on our WDW trip last fall. I wasn't a brand new beginner by that time, but I had only been golfing for about 1.5 years. We golfed at the Magnolia at 10:45 on Sunday and Lake Buena Vista at 10:00 on Thursday. My Dad and I were paired up with other people both times. The first was with a gentleman from Holland who was taking a break from an educational conference, and the second was with a lovely older couple from Pennsylvania. I really feel like meeting our fellow golfers enriched our golfing experience. I think that, above all, golf is a social sport. In each case, I explained to them that I was a relative beginner. Chances are, you won't find out if you're paired up with another twosome or solo golfer until you meet them at the starter's booth. The woman I spoke to at WDW Golf told me "you will be paired up with someone." I know they try to fill every position, if possible. With that said, the heat may scare some golfers away in August!
Two things:
1) As much as I appreciated the design and beauty of the Magnolia, I wouldn't recommend it to an inexperienced golfer. Granted, I played it two weeks before the Children's Miracle Network Classic and they were letting the rough get really tall, but I struggled the entire time and was exhausted by the time we left the course. If you always hit the ball on the fairway, I imagine it's a different experience. I... don't. I loved the LBV course, though.
2) The Lake Buena Vista course is currently hosting
DVC member golf clinics on Thursdays from 9:00 AM to 10:00 AM for $15 per person. It sounds like an excellent way to warm up and get some affordable instruction before a round!
