We just returned from combining the French Escapes and Lisbon/Duoro/Madrid tours. Both tours were very similar in activities and both riverboats and staff were great. The two tour directors we had on the Lisbon/Duoro/Madrid were the gold standard in my opinion. They were organized, energetic, informative, spoke excellent English and had a great sense of humor. It made a huge difference in our level of enjoyment. If Tauck posted the tour directors schedules, I would probably use that as a selection guide.
