I would definitely go back to Streamsong. In fact, I'd prefer to play there again between the months of November and April than take a chance on the weather at Bandon Dunes. I have no idea if the golf and the amenities will attract enough traffic in the summer months for the operation to be successful -- I won't be playing Streamsong in the summer. But the quality of golf is certainly comparable to Bandon, and it makes more sense as a winter destination.
I've played just one round on each course, walking the Red with a caddie the first day and walking the Blue with the same caddie the second day. Despite my creaky 60-year-old knees, neither course seemed like a particularly tough walk. I tend to agree that the greens on the Blue were more difficult, but their difficulty was obvious. Sometimes I had the ball in the wrong place, and I knew I was screwed. On the Red, my caddie and I disagreed four or five times on how to read a putt (he'd only caddied 7 rounds there at that point, and clearly hadn't learned the greens yet). I played with my wife, who really enjoyed both days, and a 3-handicap senior who thought the Blue greens were too undulating. I don't honestly know which course I prefer, but perhaps because I played it last, I found more holes on the Blue to be memorable.
We hope to visit Florida in winters to come, and if finances allow, I'd love to go back to Streamsong. We spent the night in Lakeland, so outside of $5 tap beers on the outdoor patio after the first round, it was pretty much just golf for our group. No $12 hot dog, so I didn't leave feeling gouged. We found the staff personable and eager to please. I suspect they'll smooth out any operational glitches fairly soon. Rich Mack may not be Mike Keiser, but my understanding is he has a lot of leeway in running the place. I know he's a fine player and knows what golfers want.
