To be honest this is pretty low hanging fruit. You have a great looking hotel from a very convenient overlook. All you have to do is wait for good conditions, which we haven't had much of lately (snow). Also the blue hour went by much faster than I would've liked.
Basic work in lightroom, then photoshop to get the colors to pop a bit and then yes I added the snow. Although it was snowing the whole time I was there I still haven't figured out how to capture. I was thinking of using a flash but of course I forgot it.
