If you are anticipating going on anything even remotely resembling a water ride, take the 18-135. If you think there might be inclement weather, likewise. I've just finished a 3 week overseas holiday with my family, and apart from ONE specific use that was planned carefully ahead (and needed the DA15/4), the 18-135 was on the camera almost the whole time and did the job well.
If you think you need more wide angle and less reach, and renting a DA16-85 is an option, you could consider that. IIRC that one is also WR.
