There's no real point in evaluating Streamsong as a destination resort until the hotel etc. is finished. Evaluating the golf is one thing, but the amenities will prove important when making comparisons.
It's already fantastic - the rooms above the pro shop/restaurant are exceptional. The game room, restaurants and outside fire pit are already way beyond what I expected.
Streamsong will only get better - it's a no brainer home-run.
