Alternatively, contact the maufacturer and ask for a list of their dealers in the area you'll be visiting.
I did this when I wanted to use some Delta 3200 in Florida a few years back. Ilford quickly gave me the details of a very good dealer in Orlando who was happy to supply the visiting Brit with film, dev, stop, fix, wet and a decent set of grads ('cos I forgot to pack mine!). He even gave me a discount because I'd come over from the UK!
The advantage of this approach is that you can restock if you run low, or conditions are not as expected.
Hope this helps,
