I went to HK recently and got a expensive room. Why!? It's because when I book it, it does have a full view of the harbour, just nice for time lapse. So, I went to get a piece of black cloth, 6m X 1m. When I got the room, it's a corner unit and I could see part of the city view too! I setup my camera with the black cloth clipping on the white curtain. I did missed out some parts at the corners but 90%, I hardly see reflection after that. Ended up with some nice time lapse from the room. So, bring a piece of black cloth in your future trip, you never know when you need it. A 3m X 2m would be a better choice.
