If you're going to the mountains, may as well go for the action and go to G'burg. Thanksgiving is busy but not overwhelming - just a long weekend. I don't see where getting a room would be a problem.
Of course, if you want to avoid the crowds, look at some of the state websites for other venues in the mountains - won't have the resort atmosphere but peace and quiet. Places like Red River Gorge Ky., Cumberland Falls ST. Resort Pk., KY., Marion, Va., Franklin, Tn., are options.
I would say neither one. Crowded, traffic and from your script, not what you want.
I also suggest coming over the NC side. Blowing Rock is a quaint mountain town, filled with awesome mountain memories, beautiful scenery, crafts, music, great food and family activities.
