I just watched the classic Grand Hotel starring Greta Garbo, Joan Crawford and both John and Lionel Barrymore.

The neat thing to me is that 70 years later, life in grand hotels is nearly the same. A great line from the film...
What do you do at the Grand hotel? Eat, sleep, loaf around, flirt a little, dance a little. 100 doors leading into one hall, no one knows about the person next to you. And when you leave, someone occupies the room after you, lies in your bed…that’s the end.
That, and the bar that is about 2 feet higher than bars these days. And Joan Crawford saying no to a cocktail and ordering Absinthe instead.
I think it's the best hotel film ever. Any others?
