You prefer learning over relaxing on your vacations. The typical Lindblad shore excursion doesn't include shopping or beach-going.
You want an active vacation in out-of-the-way destinations. Think Galapagos, not St. Maarten or the French Riviera.
You desire to travel with like-minded people who want to learn more about the world they live in.
