Opryland is an extraordinary flight of fancy and one of the largest hotels in the world with over 3000 rooms and suites. This is probably something like what would be built on the surface of the moon if NASA and the US decided colonize it - a ginormous network of glass domes and conservatory frameworks housing a village of shops and restaurants in a sub-tropical Botanical Garden. A river runs through it, and the room balconies overlook this bizarre oasis. It is a blend of Disney magic and Las Vegas extravagance - without Mickey Mouse or a single casino. Only in America. Love it.
