I wouldn't go to such a trip without the 14-24... What's the point of pairing such a great body with such a great lens without utilizing them in the most interesting places?! I know its bulky and heavy but you can it leave in the safe at your hotel when not using it.
I suggest that you take all three: 50, 14-24 & 28-70. I guess it's too late to suggest what to buy instead of the beast
