One just needs to get a 2nd drone without the remote and the charger (with 10% educational discount, its less than USD700 with a 2nd battery/more props included). The 2nd battery and additional props can be used without activating the drone (which means the 1-year warranty of the spare drone can be extended indefinitely).
After flying more than 15 hrs to a remote destination for sightseeing, one simply cannot afford to spend a portion of the vacation without a DJI drone. Agreed ?
