I've been there in March, so it should be somewhat similar conditions. The courses are in great shape (it IS Pinehurst!). They are resort conditions though....short rough....slick, but not ultra-fast greens.
When I went in March, it was my first round of the year since I live in WI/ND. The only time we could get on the #2 course was the early morning of the first round of the trip. We had 5 minutes to warm up on the range and were set on playing the unmarked tips. I'm a 3.3 handicap and all I can say is that round did not go well.
Have fun! Be sure to play the #8 as well. Don't underestimate the shorter tracks they offer as well. They can be just as fun if you want to play 36 in a day as the second nine when you might be getting wore out a bit.
