Your subjects, polar bears or family, might end up looking a little small with a wide angle lens I guess, especially if they are far away from you.
The closer, the wider, for me with a family vacation, within reason. Majestic landscapes I prefer a more 'normal' or even telephoto POV, since they are further away and look too little otherwise.
My ideal travel camera would be a TLR, or a manual rangefinder. just meter once, 1 maybe 2 focal lengths. Not too much complication, and can still 'point and shoot' at f8.
My question to your question would be 'what is your subject and how far away will it be' and choose a FOV as appropriate?
Travel and new places is awesome, whatever's in the bag. Your choice sounds fine to me and perfect composition isn't necessarily a better photographic memory/record of a place/time anyway.
