What should I do if I wanna train in Mexico

Hello, I’m looking for advice. I wanna train MMA in Mexico but I honestly don’t know the first thing about traveling. I speak the language fluently and am Mexican myself I also have my citizenship in the country so I can stay for an extended period of time with no issue. I have narrowed the gyms I wanna go to, but my family is worried and skeptical about me going by myself. Unfortunately I have no family where I wanna train. Any advise on what I should do and be looking for? I’m wanna stay for about 6 months and train.
