It's a really nice looking place, and looks like it has quite a few more things than just being picturesque going for it. If you're there for a while could you not do all of the things? (using the drone to take pictures, staring at things, looking for things? XD)
It would depend on the time of year and the day. Lately it's getting dark around 3:30pm so that's not a whole lot of light in the day when it's already quite overcast and dull. Then there's the tide, which will quite quickly catch you off-guard if you're not paying much attention to it. There are two ways to enter/exit the beach, but it's quite a long beach, and the tide can quickly cut off access to both sides.
I think it would be best to go there during spring or summer rather than the middle of December. :^)
