You are planning to travel every year to new destinations and you have not any Camera except Mobile camera, this is very shocking for me. You have to buy any Point and shoot camera.
For deciding which point and shoot camera is good for you, I would like to share one article with you. Here is article link http://www.gadgetreview.com/best-point-and-shoot-digital-camera Using this review article you can easily decide which point and shoot camera is the best for your use.
According to me you should not buy drone because of Drone is very expensive and most of the countries are not allowing you to to use drone as you already said.
One option is there, when you need drone, you can hire it on rent. This is the best option for you.
Thanks for sharing the link. I am about to start travelling to different destinations from this year, so till that time the phone camera was sufficient, and i already got the camera, Canon SX60.
