I found that there should be enough time to see at least one more vineyard or a tourist spot. This tour only offered 1 vineyard in Saint-Emilion and 1 in Pomerol; there is sufficient time in between.
Tangier is an interesting place to see. We had 2 guides. The first one took us from Malaga did not talk much but he kept us on time. We were almost the first batch to board the bus and it took us about 2 hours to get to the ferry. Within these 2 hours people got picked up from various hotel locations. The second tourist guide was a local Tangier resident and he spoke 5 languages. He has tried to tell us the culture and a bit of history about the local area. I personally don't like to visit the carpet shop nor the spice sale as these two shopping activities were not described in the tour. Besides, it had engaged too much time. The local people had been chasing us to sell their stuff since we got off the bus.

It was well organized and Kevin (the guide) was knowledgeable and humorous. The bus was comfortable. It was too short to explore every place but would have preferred to spend more time in Oxford and Windsor.~K
