Nina, Generally when I travel for business I don't have "personal" time. However, a great deal of my business travel involves 'entertaining' (as does a great deal of my time in NY), so I am able to get to know a little about the place I'm visiting, and experience a restaurant or cultural event or two.
I know it's something that people don't understand, but it's hard work 'entertaining' for business. There are some dreadful bores who I have to pretend I think are the most wonderful people I've ever met. And there are the ones who you can't do enough for. Fortunately, though, most are people who I enjoy meeting and developing a relationship with. It takes alot of energy, though. I always have to be "on". Rather like a performance, at times...
