Eating on Semester at Sea

As many of you have heard me brag about recently, i will be going on a 3.5 month journey with Semester at Sea. If you have not heard of semester at sea i suggest you check out their website SemesteratSea.org.
It is a college campus on a cruise ship that goes around the world giving students the opportunity of a lifetime+ college credits.
I will be visiting many countries, and although I have my triumph dining cards, many languages and cuisines are not covered in these tiny cards and any help that the forum can provide would be REALLY appreciated!
I will be visiting many areas in each country in addition to these port cities where the boat will be docked:
1) Cadiz, Spain (salmanica,granada, rhonda,arcos, sevilla ect...)
2) Casablanca, Morrocco (rabat, Marrakech, Volubilis/Fes ect...)
3) Acra, Ghana (Togo, Benin and Ganvie ect...)
4) Cape Town, South Africa
5) Port Louis, Mauritus
6) Channai, India (Kancheepuram/Mamallapuram, Agra, Varanasi, Nagarkoil)
7) Ho chi minh city (saigon), Viet nam ( also cambodia, Ha Noi and Ha Long Bay, Mai Chau Village, Nha Trang ect...)
8) Hong Kong/ Shanghi, China (bejjing, xian, Guilin/Yangshuo, Hangzhou, great wall ect...)
9) Yokohama/Kobe, Japan (Osaka, Tokyo, Ritsumeikan Univ. ect...)
10) Honolulu / Hilo, Hawaii, USA
11) San Diego California
12) we will be leaving from Halifax, NS, Canada August 28 but i will be there the night of the 25th till then so recommendations for halifax are also greatly appreciated although as with Hawaii and san Diego, i am not too worried about communicating my needs
Thanks for your help!

Also! Any advice for eating on a cruise or college dining room that is buffet-style would be helpful. I spoke to them RE: celiac and they said that they would let me know which foods are safe each day and that they have had many celiacs and other students with allergies survive it
Also any recommendations for packaged foods that I can pring along that can offer some nutrition and not just calories are appreciated
Thanks again!
