I have a friend who said she was at the montage (hotel on beach here in Laguna Beach) and she went out in her balcony in the morning and to her surprise there was a drone just outside her sliding window and balcony, with the camara pointing staight in their room. She said it was incredibly violating and told the hotel. When it left, it slowly went down to look in other rooms. The hotel didn't know anything about it.
My initial instink is that it is too bad someone didn't have a pellet gun or one of those .22 shot rounds for small rodents or snakes.
Not sure what the safest answer is, but someone will start making something (paintball gun?, air soft shotgun?).
Can't help but think that this was some pervert looking for a free show or looking to see if the place was vacant and easy to break in. Either way, something isn't right. And it has the feel horrible to sit there and watch it and feel helpless.
