Just make sure your film doesn't get x-rayed at the airport.
Carry-on screening x-rays are OK, but unprocessed film in checked baggage will get fried.
There are film disposables being sold here as "digital" because after-processing digital scanning of the film is an included feature. From the article posted by Ohrryp, I don't see the real digitals being a worthwhile purchase, at this point. I haven't actually seen them here anyway.
From what I've seen, the disposables shoot as well as super cheap 35mm point-and-shoot cameras. I wouldn't buy a conventional film camera at this point unless I was going high-end for the purposes of artistic commercial photography. If you're only going to shoot 20 or 40 shots, a disposable or two will do just fine.
Have you considered springing for a cheap digital camera? (2-5 MP, 3x optical zoom, $150 to $300) You won't have to worry about the cost of film and processing (or getting your film fogged by x-rays). It should do fine for snapshots at TAM, posting stuff in the internet, sending by email, and even prints. And, if you decide in the future to get a more serious camera, it's always good to have a backup. I take my 35mm SLR kit with me traveling, but also carry a pocket sized 3MP digital, and on our last vacation we shot about 1/5 of our total pictures with the digital. It's such a useful tool, I would recommend one for everyone, even people with more serious photographic equipment.
