You meet the most interesting people traveling with a group. In my mind, I called them "The Captain and Tennille." He always wore a sporty red captain's hat, and her name is Toni.
Always dressed to the nines, the first day she wheeled him all over Paris wearing spiked heels. After that she changed to more sensible shoes, but they were still stylish.
At first I thought they were father and daughter. The age difference was about right. I later learned that he's Phil Maloof, whose family owns the Sacramento Kings and the Palms Casino in Las Vegas. Toni is his nurse and accompanies him on trips anywhere he wants to go.
We learned all about his collection of cars and theatre pipe organs and his house in Las Vegas.
Watch this YouTube video, and you'll see him just the way he was on our trip. Somehow I don't think these guys believed that Toni is his nurse, but she really is. She took care of him after his heart attack, and she's been with him since.
