I called SW the other day to ask them about this - specifically, if they expected it to be available this December. The woman I spoke with said it's brand new and that they literally just started it a week or two ago. She said so far it seems to be going well but didn't know what the future plans are for it. I'm hoping they decide to continue with it and that it will be an option for us when we go in December. It looks like a great tour and I hope someone on these boards has done it and can share their experience.
