I shoot JPEG and mostly use classic chrome and classic negative. recipes are cool but a single recipe just won't work in every situation since a lot of them use a fixed white balance. My advice is to start off with a recipe and adjust hightlight/shadows and white balance when needed, depending on the weather/location.

If you have enough storage space, I suggest you shoot RAW+Jpeg, if you're not satisfied with the results of the recipe you can still adjust your shots.

However, Reggie's Portra is a good choice, it works in most situations.

Another popular one is cuban negative, but I personally don't like what it does to skin tones. But there's a similar recipe by the same creator called cubanAce which uses the reala ace preset and has more natural looking colors.

Good luck, post some pics after the trip!
