I have to say that the Greenbrier is the most amazing place ever. We had a fantastic time and the hotel and amenities are out of this world. Everyone in our family enjoyed it...my youngest sister who is single, my middle sister with her husband (no kids yet) and my family with 2 - 3yr olds and my parents. Everyone had tons of activities and I love having fancy dinners every night. Yes, it is coat and tie at some of the restaurants and at least a jacket at all. I love that!! But then again I like fine dining. :-)
If you ever have a chance to go (and someone else is paying...like the parents) then jump all over it!
