If I were going - I'd bring the longest glass I owned, for the birds and wildlife. I'd bring a 24-105 or similar, and I'd bring my 28/1.8 for whatever night time fast lens and/or wide use. And I'd bring one of my M4Ps, with a 35/2.0 and some film, as backup.
I travel much, hate to be burdened with gear.
Instead of trying to immerse my technology into my environment, with me behind it, I'd rather immerse myself into my environment, and use whatever I've got. Based on images I've got from the early 70's, when all I had was a match needle Nikkormat and a 50/2.0 lens... I can say - less is more, for me.
