Part of the Tokyo Dome City complex, which includes the baseball stadium, this massive hotel (with more than 1000 rooms) is smack in the middle of the city with direct access to Narita Airport, via the Limousine Bus. Rooms are spacious, though ordinary. A plus in summer is its outdoor pool.
Some packages include baseball tickets, and if you're a guest here you can also buy a discount ticket for the adjacent amusement park.
