Harbor Grand Hotel

Harbor Grand Hotel is a location on the Island in 2287.

Background
Built before the Great War, the hotel was a luxury establishment that catered to the wealthy and prominent guests visiting the Island. Among those who stayed at the hotel included Arnold Wabash, captain of the nuclear American submarine USS Democracy and his mistress Franny Richardson who later shot and tortured him into giving her the nuclear codes for the submarine. He did, but before she escaped he shot her dead before succumbing to his wounds.

Layout
A hotel located on the southern edge of the Island, overlooking cliffs that drop sharply to the water. It is inhabited by super mutants and mutant hounds.

Head out past the pool to the planks overlooking the water, and turn to the right. There is a pipe that can be reached through a series of skilled jumps or by using a jetpack that contains the drain corpse note.
