Bit of an eclectic mix of options, there, Paul.
Ask yourself what you're shooting. If it's day-lit snow scenes, you can probably get away with 100 / 200 ISO film. If you want to shoot the evening's apres-ski, then something a bit quicker (ideally, something that you can push).
Colour or black and white?
My suggestion is
not to do as I did when I was your age. Don't take a load of cameras and a load of various films. "Start with an end in mind" is always a good piece of advice from where I stand. One reliable camera and a few suitable lenses is plenty.
A Leica M4 is always a cool piece of kit for a trip - as is an F2. As the F2 has a meter (which I'm presuming is still working) I'd tend to go for the F2.
Incidentally, if you're shooting snow scenes, add 1 to 2 stops to the camera's exposure reading. If not, the reading will be based on the snow - which the camera will try to turn mid-grey. Consequently, you will end up with muddy, under-exposed photos with no highlights and blocked out shadows.
Better still, if you can get your hands on a hand-held meter that provides incident readings, use that as it measures the light falling onto the snow (much more accurate with snow and water scenes), not the light being reflected off it. A camera's on-board meters provide "reflective" readings.
Enjoy your holiday......
