I could but I don't really want to carry a dark bag & tank & chemicals if I can avoid it. I figure that since I won't be equipped to do all my film, why bother processing any of it?

I wouldn't mind processing the film locally from time to time but I'm worried that I won't be able to find and vet good labs. In the US, it's getting harder and harder to find places. I usually ship my E-6 film out to be processed since the last local processor in town is now closed. The local C-41 lab does a terrible job (mishandling negatives, mixing up orders, etc).

I have no idea what to expect in Mexico, Central and South America. How do film hobbyists in those locations process their film? Are there any labs I should add to my list of destinations?
