I played at The National a good number of times over the winter season because it was reasonably priced and available for public play although always very crowded and slow. I thought it was a credible course and design for a Florida residential development. They did a nice job of creating rolling and undulating fairways and the greens had some nice movement in them. Given it was new, the conditions were good.
I rarely look at the yardage from the tips as there's no point in me trying to play there. I went two up from the tips at just over 6000 yards. I tried the tee back from there a couple of times, but the two long par 3's on the front nine were driver for me playing to the north into the winter wind and were just lost ball territory.
I suppose they put the little tee pads for the tips far enough back to be able to advertise the course as championship but I can't imagine anybody from a Florida residential community actually playing from back there when they take it private. The good news is that the design of the holes routed between the housing streets is such that there is virtually no back-tracking the tip tees - you just drive right on by them and they're small enough that they'll require minimal maintenance. Being a residential course it is designed for cart ball. The bad news, now, is that the housing development is just underway so there is a lot of heavy construction for sewers and water etc. resulting in many areas where the cart paths are through dusty gravel and broken ground.
The combination of holes is interesting in that the two long par 3's are on the front offset by two shortish par 5's. The back nine is the opposite with two short par 3's and two long par 5's. The par 4's are a good mix of short, medium and long holes.
It was a worthwhile place to play in an area where there is a dearth of reasonably priced and nicely designed and well maintained courses.
