>is 35mm and 120mm readily available<
I don't know about the 120mm, 35mm can be bought all over, but the costs down there are outa site. I take 20 to 30 rolls per 1 wk trip and if you consider paying 50 to 100 percent more per role and don't mind paying for it go for it. Other things to consider is if they have the iso/asa speed you want, how about print or slide film? Pro or over the counter films, will you 'push' any film? Also the freshness is a factor in film quality, film does not like heat and high humidy, you can loss color balance if exposed to either for a long period of time. So it really depends on your needs and budget.
>and is there a place for processing on the caye.<
I'm sure there is, but then again the processing cost could floor you.
>finally, are there any comments about photographic film being x-rayed at the airport(s). anybody's film fogged? suggestions? <
Never had a problem, they use such low levels of radiation that it takes a lot of trips through the detectors to do any damage. I would be much more concerned with your photo skills to produce quality photos than the x-rays.
If you are really concerned about the x-rays you could wrap the film in lead, but be for warned it is not worth the hassle.
