Q. You just had a great show on travel. You covered kids, insurance and even pets. But what about the solo traveler and those crippling single supplements? I have found just one company -- GAP Adventures -- that doesn't penalize the solo traveler with these fees (which can be substantial). Can you help us out with some research on other companies that welcome (instead of penalize) us?

A. As more and more travelers fly solo, single supplements are a growing problem. A great article offering some solutions is this New York Times article on the topic. I've inspected the Norwegian Cruise Lines "studio" cabins mentioned in the article, and I think they're a great solution to this problem. The article mentions Grand Circle Cruise Line, but Grand Circle also offers land tours with very low or non-existent single supplements on many departures.
