Hi Dawn, the doctor in me feels the need to answer your question about vaccinations, haha! I'd recommend making sure you are immunized against Hepatitis A & B (there is now a single shot to immunize for both- in Canada it's called Twinrix). A bunch of us also took the oral vaccine, Dukoral, prior to travelling, and I think it saved some of us (protects against a strain of bacteria causing traveller's diarrhea). I also suggest you get a prescription from your doctor for an antibiotic just in case you get a really bad case of traveller's diarrhea, which does not let up.
