Canyon Ranch in Lenox
A second vote for this property. It can't be beat for the all-around experience, and there will be men there. There are some newly renovated executive rooms that I want to check out on a future visit.
I haven't been to Woodloch, but it strikes me as more of a couples/female place. Even if it's newer, it doesn't have the facilities, the array of activities, and the staff that CR does.
