I really like the walls of the hotel, but I think the roof kind of takes that whole awesomeness away. The plain studded plate roof could have used some more tiles, or a different roofing technique if you ask me.
The walls are very well made though, with SNOT techniques to get the pattern right. I can't exactly put my finger on why, but that gate in the middle looks very inviting to me.
The big yellow castle is just plain awesome, the amount of yellow bricks needed to make the 6x bricks is impressive and that they actually built it there on site with the actual 6x bricks is even cooler, it's not just a 6x magnification of the castle, it's a true 6x magnification of the set and all its parts. In theory you'd need 216 (6x6x6) original yellow castle sets just for those parts. Even though I'm sure there were more sources of yellow parts, where would one get 2592 yellow slope 75 bricks?
I love this!
Just look at this photo
, with all the parts lying around, I'd be proud if I could even build a few of those bricks, let alone the whole yellow castle
