Jim,
I played Seaside last week, in the afternoon after the conclusion of the SEC Golf Championship. I've had the good fortune to play Seaside 5-6 times over the last 15 years, and the condition of the course last week was simply spectacular. Perfect greens, firm conditions throughout, the usual dose of wind and green surrounds cut very tightly, much tighter than I remember from past visits.
I really love Seaside, and I think it is one of the finest links courses I have played in the USA. Why it is not ranked higher in the usual lists is a mystery to me.
The green fees are pretty steep, but, in my opinion worth every penny. I don't know about any of the other courses in the area, but Seaside is an absolute must play.
