Unless you use a very intricate dwc system with a large reservoir and auto 'top-up' mechanism, you Will have problems leaving your plants alone. If you absolutely have to leave for longer than 3-4 days, I would go soil with an automated dripper system.
I run a small scale dwc system and at times, maintenance can be quite hefty; Ph will start to fluctuate, water will need to be added to maintain levels, and fert might need to be added if they are using it too quickly. But don't let me discourage you! If you are willing to design a system based on your needs, you will be well rewarded, dwc is the only way to go in my opinion.
Also, are you going to be using an exhaust system of any sort? Ventilation will be necessary in order to grow healthy plants. If you have a good ventilation system, I would recommend using your hps through veg as well as flower, more light is always a benefit.
Keep us updated on your progress. Good luck!

A dilute nutrient solution will actually increase Ph fluctuation I believe. Most good hydro nutes have a Ph buffer in them that anchors the Ph to an acceptable level.
Is there any way you could visit them once or twice over break? Also, you will have to adjust your lights during that two week period.
