I actually talked to someone the other day at Tobacco Road and asked if they could access Dormie. She said they did have access to the course, even though it is not listed on their website. She couldn't quote an exact price (said very few had ever asked them about it), but she thought it was about $200 w/a forecaddy included.
I've never dealt with the people at Talamore, but if anyone is looking for a Pinehurst package I would very highly recommend the group at Tobacco Road..VERY easy to work with.
