Doug, are you hauling a cooler to keep that film useable and a lead bag to keep the xrays from ruining it? You'll want 800 - 1000 asa to capture the animals, at minimum 400 film.
Sadly, it's so hard to travel with film with the TSA regulations. I think that's been a blessing for the camera manufacturers - everyone is buying new digital equipment. You will really enjoy your new Canon. I am thinking of getting one of the Elph's for snapshots when I am walking around being a tourist and not a photographer.
