By the way....

I'm thinking OP is in an age group where film is "new". Over the last few decades, there were all sorts of cheap cameras made with inaccurate or no metering what-so-ever. Many point and shoot and ALL of disposable cameras are this way. Yet, they often produce good images. Negative films aren't that sensitive to small errors. It's WAY more forgiving in magnitude of several stops when compared to digital. Don't worry so much.... Enjoy your trip and the company of whomever you'll be traveling with. You'll be fine....
