The Hotel New Hampshire by John IrvingRead about the other entries on the list.
One of Irving's sweeping modern-Dickensian novels, it follows the various dramas of a family in two separate hotels, each called the Hotel New Hampshire. Among a huge cast, there's an author who kills herself as a result of writer's block, which possibly isn't the sort of thing you want to read while researching a novel about hotels.
