In my opinion, electronics and communication engineering is better because it has utility in wider range of sectors from IT industry to manufacturing plants. As technology is changing at a great pace, most of the innovations and technology changes are in digital world and communication networks.
On the flip side, petroleum engineering has a concentrated scope of work. Though, incentives and pay of work is more as compared to other fields. Even change of field is easier in EC as compared to PE.

Nano technology do have future scope. There are newer technologies in medical imagining based on nanotechnology. Petroleum as we all know is a non-renewable resource, but still there are many parts of world known to have oil reserves, which are still unexplored.

Petroleum engineering is a professional degree, where as hotel management is not. If you don't want to worry about studying then choose hotel management. Hotel management is mostly practical based. You can just enjoy doing it. In the present scenario where crude prices are low and many have lost their jobs because of this, its better stay out of it. One more thing, its really unethical to compare these two courses as they are like two different poles. First, be clear whether to do engineering or normal degree. You can also consider courses like marine, harbour, nautical science etc.
