You sure jump to a lot of faulty conclusions, robb.
First the couple isn't married which is none of my business; second, it was the couple who suggested that we bring the intern along for the experience. Third, they are all three very good friends who really enjoy one another's company both on and off the clock; and, fourth, the original suite had a completely private bedroom and living room area at the HGVC.
We are a small company where everyone gets along with each other very well, and that probably makes a huge difference.
You are absolutely right that I would not have incurred the expense of taking the intern along if the three of them had not come up with a cost-effective way to make that happen.
As it happened it all worked out beautifully to everyon'e satisfaction.
