Bill Spellman,
Lighthouse Sound had a TON of environmental considerations that certainly led to the sprawling, non-intimate routing and I don't hold that against Hill.
To his credit, and I'm sure to the owners wishes, he did certainly try to create something memorable, splashy, photographable, and challenging, and it is hardly your typical "resort" course.
In fact, it's brutally difficult.
As you know, that site is perenially windy, and my biggest complaint is that the greensites that were constructed would have been difficult on the most placid inland course. Most are elevated, very firm, with severe fall-offs into deep bunkering, wetlands, and other forms of torturous golf. When you factor in the minimal 15mph wind out there, I had to wonder exactly who the course was built for.
The following link best exemplifies what I'm talking about. Just imagine trying to hit this green with a 3-wood into a spanking wind.

If this course is popular with vacationers, it has to be the home of the 6 hour round and 3 sleeves of balls.
As far as Rum Pointe, I would certainly recommend a visit if you live near there. While subject to many of the same winds, it is much more forgiving, contiguous, and playable. There are a number of trademark Dye features out there, some of which work well, and others like the 9th and 18th encircling opposite sides of a lake that is frankly tired and stereotypical. I think many of the green complexes are pretty well done, and a few holes and particularly approaches get the blood pumping, but it's perhaps a little too placid and even forgiving out there, overall. In particular, I found there to be very few holes that made you think much from the tee, and that is somewhat unlike Dye. At best, it's a Doak 5.
I'd be curious to hear your thoughts if you get over to either course.
