Actually, we visited the Rijksmuseum in 2011 on a Christmas cruise with another cruise line. They had the Vermeer exhibition at that time and it was included in the cost of the cruise. WONDERFUL.
We had the opportunity to stay at the museum while everyone else when to the diamond factory (not interested) so we headed right back to the ship and never regretted it. Barely made the bus!
Yes, I loved the Van Gogh tour when in Conflans. (I simply cannot pronounce Auvers-sur-Oise :D) The day was rainy, dark and gloomy - perfect for Van Gogh, but we walked it all and the young man who was our tour guide was excellent and passionate about his subject.
(Doesn't that tell all!) Sorry, I digress, but it was a wonderful trip. Florence
