They have been to:
1) New York to Saint Thomas, Virgin Islands (North America)
2) to Oxford, England (Europe)
3) to Shetland Islands, Scotland (Europe)
4) to Copenhagen, Denmark and Malmo, Sweden - or are they separate legs? (Europe)
5) to Marrakech, Morocco (Africa)
6) to Outer Morocco - perhaps desert? (Africa)
7) to Sicily, Italy (Europe) speculation thus far.
What a season so far, a visit to Israel or Jordan would be awesome from Italy - and India, Philippines and Australia might be a nice end to the season in terms of Asia and Oceania. The last two of the three were on the lists to visit but were cancelled in previous seasons I believe?
