Several day trips were offered. We chose to see Gibraltar and Morocco. It took over 3 hours by bus/ferry to Gibraltar and over 4 hours to Morocco. Get on line immediately on the ferry to get your passport stamped.
We had about 3 hours in Gibraltar. Tour gave a history of the fort and we got to hang with the little apes. We had time to have lunch, shop, and walk around, too. Not a bad day trip.
All we did in Morocco was have lunch (the food and belly dancer at Morocco in Disney's Epcot center was better) and went to a bazaar (building with several stores) where they gave us a detailed explanation on carpet making (sales push). Street peddlers were also very persistent. It's still a third world country and decent bathroom facilities were very difficult to come by. Day trip is not recommended. We only had about 2 hours to tour and spent over 8 hours traveling.
